St. Isaac's Cathedral (Cathedral of St. Isaac of Dalmatia) is the largest Orthodox church in St. Petersburg. Located on St. Isaac's Square. Cathedral of the St. Petersburg diocese from 1858 to 1929. Since 1928, it has the status of a museum (the museum complex "State Museum-Monument" St. Isaac's Cathedral "").

The modern building of the cathedral is the fourth St. Petersburg church in honor of St. Isaac of Dalmatia, built on the site of a cathedral designed by Antonio Rinaldi. The author of the project of the fourth cathedral, which was intended to become the main Orthodox shrine of the empire, was the architect Auguste Montferrand. The construction was supervised by Nicholas I himself, the chairman of the Commission for the construction of the cathedral was Karl Opperman. During the construction of the building, new construction technologies were used for that time, which influenced the further development of architecture in the 19th and 20th centuries. The construction of the building and work on its design continued from 1818 to 1858. St. Isaac's Cathedral is considered the latest building in the style of classicism.

It was consecrated in the name of the Monk Isaac of Dalmatia, revered by Peter I as a saint, since the emperor was born on the day of his memory - May 30 according to the Julian calendar. The solemn consecration on May 30 (June 11), 1858, of the new cathedral was performed by Metropolitan Gregory of Novgorod, St. Petersburg, Estland and Finland.

Registered in June 1991, the church community received the opportunity to worship in the cathedral. Divine services in St. Isaac's Cathedral are held daily. The rector of the church is Metropolitan Varsonofy (Sudakov) of St. Petersburg and Ladoga.

 

Cathedral history

St. Isaac’s Cathedral (Saint Petersburg)

First St. Isaac's Church

The first temple was built for the Admiralty shipyards, which by 1706 employed more than 10,000 people. Peter I gave the order to find a suitable building for the future church. The building of a large drawing barn was chosen, which was located on the Admiralty meadow, opposite the gates of the Admiralty. The money for the restructuring was allocated by the Chancellery from the buildings of the city, which belonged to the Admiralty Department. The Dutch architect Harman van Bolos was invited to build the church spire. The building was wooden, one-storied, of a simple form. On the roof there was a bell tower with a spire and a small dome with a cross above the altar. The church was founded on the day of St. Isaac of Dalmatia in 1710, in the same year the first service took place.

Here, on February 19 (March 1), 1712, Peter I and Ekaterina Alekseevna were married. There is an entry in the log book for that day:
In the coming year, which no longer represented the expectation of adversity, Peter I married Ekaterina Alekseevna on the 19th, on Tuesday, during the omnivorous week. The wedding of His Majesty was performed in the morning in St. Isaac's Cathedral. At 10 o'clock in the morning, the highly married, with volleys from the bastions of the Peter and Paul and Admiralty fortresses, entered their winter home.

The first church was demolished when it became clear that it was too small for the rapidly developing city. It was decided to build a second church near the Neva, just 20 meters from the shore, where later a monument to Peter I was erected instead of the church, according to other sources, the church was built a little east of this place.

 

Second St. Isaac's Church

The second St. Isaac's Church, in stone, was founded in 1717, since the first one had already dilapidated by that time. On August 6 (17), 1717, Peter I personally laid the first stone in the foundation of a new church in the name of Isaac of Dalmatia[2]. The second St. Isaac's Church was built in the style of "Peter's Baroque" according to the project of the prominent architect of the Petrine era, Georg Mattarnovi. After his death in 1719, the construction was headed by Nikolai Gerbel. By this time, the foundations had already been completed. A report to the Chancellery from the buildings of the stone craftsman Yakov Neupokoev has been preserved: “After the death of the architect Mattarnovi, the construction was entrusted to the architect Gerbel, who does not indicate what to do, and there is a stop in the building.” Gerbel erected the church vaults, but after they cracked due to unsuccessful design decisions, Gaetano Chiaveri was handed over the construction management. The church was completed by stone master Yakov Neupokoev. The decoration was completed first by Chiaveri (1725-1726) and then by Mikhail Zemtsov (1728).

The church had three naves, with side porches and, for the first time in Russia, had the shape of a Latin cross in plan. The stucco facades were almost devoid of decoration, the side vestibules were articulated by pilasters with capitals, their pediments were decorated with cornices of a laconic profile. The walls of the side façades were divided by double blades of a quarter brick, located between the arched windows. The windows were glazed with Yamburg mirror glass - the local factory had been operating since the times when these lands belonged to Sweden. Under the windows, as well as under the windows of the Kunstkamera and the palace of Tsaritsa Praskovya Feodorovna, Gerbel arranged niches. Apse, vestibules, side naves had vaulted brick ceilings. The “octagon on the quadrangle”, placed at the crosshairs of the vaults, crowned the octagonal dome with a star. The steeple on the bell tower and the dome were built according to the design of van Boles in 1724. The hip roof with a horizontal break was covered with iron along the board. The plan length was 28 fathoms (60.5 m). The width from the southern doors to the northern ones is 15 sazhens (32.4 m), in other places - 9.5 sazhens (20.5 m).

The appearance of the church was reminiscent of the Peter and Paul Cathedral[12], this similarity was even more enhanced by the slender bell tower with a clock-chimes in the third tier, brought by Peter I from Amsterdam along with the clock for the Peter and Paul Cathedral. The height of the spire of the bell tower was almost equal to the height of the spire of the Admiralty tower.

The bell tower was 12 sazhens and 2 arshins (27.4 m) high, the spire was 6 sazhens (13 m). The onion-shaped spire was crowned with a weather vane - a gilded angel holding a cross (the weather vane of the Peter and Paul Cathedral is a cross on which an angel stands).

Five architectural sheets signed by Gerbel have survived. Among them are four versions of the iconostasis, the only sketches of altars from the time of Peter the Great that have come down to us. The carved gilded iconostasis, similar to the iconostasis in the Peter and Paul Cathedral, was made in the Moscow workshop of Ivan Zarudny. In 1763, before the demolition of the church, it was dismantled and sent for storage to one of the temples; nothing is known about its further fate.

On June 26, 1733, the bell tower burned down from a lightning strike, restoration work was carried out by van Boles. In the same year, 1733, the bell tower was rebuilt, and in the following year, the clock for the church was also made. In May 1735, a lightning strike caused a fire in the church, and it was seriously damaged. Thus, for example, the cabinet minister, Count Andrey Osterman, describes the state of affairs in the church, asking on May 28 (June 8), 1735, permission from the Synod to arrange a church in his house for his sick wife and appoint a priest there:
The Church of St. Isaac of Dalmatia, from whom my house is acquired in the parish, has recently burned down and services in it are not only liturgy, but also Vespers, and Matins, and hours, now there is no.

Already in June of the same year, an estimate was drawn up for the correction of the church. Two thousand rubles were allocated for these purposes, and Major Lyubim Pustoshkin was appointed to supervise the work. The relevant decree stated:
The Church of St. Isaac of Dalmatia, how soon it is possible to begin now, although only over the altar to quickly cover with boards, and then over the whole church to contract to make rafters and roofs, so that now there could be a service in it.

As a result of the repair, according to the project and under the supervision of the architect Pietro Trezzini, the walls and galleries were rebuilt, instead of iron, the dome was covered with copper, and the vaults were replaced with stone ones. Services began to take place again in the church. But in the course of the work, it became clear that, due to the subsidence of the ground, the temple needed more corrections or even a complete rebuilding.

The location of the church next to the Neva (on the island of New Holland), the shore of which had not yet been fortified, was unsuccessful - this was the conclusion of the examination of the architect of the Admiralty College Savva Chevakinsky. Water from the Neva, as well as water discharged from the Admiralty House, undermined the foundation of the building. According to some sources, Chevakinsky stated the impossibility of preserving the building and decided to dismantle the church and build a new one further from the coast. According to others, work on the restructuring of the church was carried out in the same place

 

Third St. Isaac's Cathedral

By a decree of the Senate dated July 15, 1761, Savva Chevakinsky was entrusted with the design of a new building. The project was not implemented, but it was Chevakinsky who came up with the idea of moving the church further from the river - in one of the options, the place for it was chosen where the modern cathedral is located.

Catherine II approved the idea of recreating the bell tower of St. Isaac's Cathedral, but in its former forms, without taking into account the Chevakinsky project, which proposed a completely different look for the cathedral. Soon Chevakinsky resigned. In 1766, a decree was issued on the start of work on a new construction site, planned by Chevakinsky. On January 19, 1768, Catherine II signed a decree "On the manufacture of marble and wild stone for the construction of St. Isaac's Church in the Keksgolmsky district of graveyards Serdobolsky and Ruskealsky with the installation of grinding mills there." The ceremonial laying of the building took place on August 8, 1768, and a medal was knocked out in memory of this event.

The new design of the cathedral was designed by Antonio Rinaldi. The building, as conceived by the architect, had five domes of complex design and a high, slender bell tower. The walls were covered with marble throughout. Circumstances were such that Rinaldi could not complete the work he had begun. The building was brought only to the cornice, when, after the death of Catherine II, construction ceased, and Rinaldi went abroad.

Paul I, who ascended the throne, instructed the architect Vincenzo Brenna to urgently complete the work. Brenna began work on April 1, 1798. At first, the architect intended to follow the design of Rinaldi, but soon, due to lack of funds, the architect was forced to distort the design of Rinaldi. By that time, the cathedral had been erected to the base of the drums of the domes. Brenna had to reduce the size of the upper part of the building and the main dome and abandon the construction of four small domes, as well as reduce the height of the bell tower by one tier. Marble for facing the upper part of the cathedral was transferred to the construction of the residence of Paul I - the Mikhailovsky Castle. The cathedral turned out to be distorted proportions, squat, with a strange combination of luxurious marble plinth and brick walls.

This building caused ridicule and bitter irony of contemporaries. The following epigram was widely used in various versions:
This is a monument of two kingdoms,
Both so decent:
On the marble floor
A brick top has been erected.

 

Modern St. Isaac's Cathedral

In 1809, a competition was announced for the construction of a new church. An indispensable condition was the preservation of the three consecrated altars of the existing cathedral. The program of the competition, approved by Alexander I, was compiled by the President of the Academy of Arts Alexander Stroganov. It said:
To find a way to decorate the temple... without covering... its rich marble clothes... to find a dome shape that can give grandeur and beauty to such a famous building... to come up with a way to decorate the area belonging to this temple, bringing its circumference into proper regularity.

The competition was attended by architects Andrey Zakharov, Andrey Voronikhin, Vasily Stasov, Giacomo Quarenghi, Charles Cameron and others. But all the projects were rejected by Alexander I, since the authors proposed not to rebuild the cathedral, but to build a new one. In 1813, under the same conditions, a competition was again announced, and again, none of the projects satisfied the emperor. Then in 1816, Alexander I instructed the engineer Augustine Betancourt, who had arrived from Spain, chairman of the newly formed "Committee for Buildings and Hydraulic Works", to start preparing a project for the restructuring of St. Isaac's Cathedral. Betancourt offered to entrust the project to the young architect Auguste Montferrand, who had recently come from France to Russia. To show his skill, Montferrand made 24 drawings of buildings of various architectural styles (however, technically not justified in any way), which Betancourt presented to Alexander I. The emperor liked the drawings, and soon a decree was signed appointing Montferrand "imperial architect". At the same time, he was entrusted with the preparation of a project for the restructuring of St. Isaac's Cathedral with the condition that the altar part of the existing cathedral be preserved.

Project of 1818. Start of construction
In 1818, Montferrand, following the instructions of Alexander I, drew up a project that provided for the preservation of most of the Rinaldi Cathedral (the altar and domed pylons). The belfry, altar ledges and the western wall of the Rinaldi Cathedral were subject to dismantling, the domed supporting pylons of the southern and northern walls were preserved. On the north and south sides it was supposed to build columned porticoes. The cathedral was to be crowned with one large dome and four small ones at the corners. The height of the vaults remained the same, and this circumstance complicated the development of the project, and the overall composition of the building was disproportionate: a monumental portico, a large central dome, supplemented by small ones placed at the corners, “pressed” it. The design of the cathedral in this form was approved by the emperor in 1818. In the 1820 edition of his project, Montferrand included an image of the interior of the cathedral, which gives an incorrect idea of ​​its internal perspective: the drum with window sills would not be visible from where the viewer is.

As N. P. Nikitin notes in his monograph, when creating the project, Montferrand took as examples the building of the Parisian Pantheon (a dome with a colonnade, a portico, an internal processing solution) and the Invalides (the structure of the dome ceiling). The Montferrand project (in terms of the architectural composition, but not the decor of the building) was not an original work, but a compilation, which was the custom of many, even the largest architects of that time.

In an effort to preserve the Rinaldi Cathedral, Montferrand provided for an increase in the size of the building only in the east-west direction, so that it became rectangular in plan with an aspect ratio of 4 to 7. Four new pylons increased the width of the building by the width of the transverse nave. Taking into account the new porticoes, the plan turned out to be an almost equal cross. Two old pylons, reinforced on the western side, and two new ones became a support for the dome. Rinaldi designed a chapter with a diameter equal to the side of a square base, Montferrand put a new chapter on the same base, the diameter of which was already equal to the diagonal of the square. Thus, the drum of the new chapter hung over the vaults of the side aisles. Together with the columns surrounding the drum, the diameter of the new dome was two-thirds larger than that of the Rinaldi one.

Construction management was entrusted to a special commission. Its chairman was a member of the State Council, Count N. N. Golovin, members were the Minister of Internal Affairs O. P. Kozodavlev, the Minister of Spiritual Affairs and Public Education, Prince A. N. Golitsyn, engineer A. Betancourt.

The organization of work, the entire economic part of the construction was entrusted to the commission (according to the regulation on the commission, approved only in July 1820), the management of the actual construction work, the solution of all technical issues and the management of the architect's actions were assigned to Betancourt. Quality control of materials was entrusted to the architect. A special commissioner was appointed for their acceptance and storage. Betancourt, busy with work at other sites, often absent from St. Petersburg, limited himself to attending meetings of the commission and resolving issues on the construction of the bases and foundations of the building.

On June 26, 1819, the solemn laying of the new cathedral took place.

 

Work of the Maudui Comments Review Committee

In 1820, Montferrand released an album with 21 engraved tables. To his two plans, which remained unchanged, he added a longitudinal section, a general plan, a design for a church designed by Rinaldi, as well as wall painting designs, two perspective views, and a depiction of an interior. The project again attracted the attention of specialists. The architect A. Maudui, who was one of the members of the "Committee for Buildings and Hydraulic Works", entered with his sharp criticism. On October 20, 1820, he submitted a note to the Academy of Arts with comments on the 1818 project. The note was accompanied by drawings showing Montferrand's mistakes.

Maudui petitioned for the cessation of all construction work, except for masons and dismantling of those parts of the structure that were intended for demolition. On June 14, 1821, at a meeting of the Academy of Arts, the creation of a special committee to consider Maudui's comments was announced. At the first meeting of the committee (in August 1821), two letters from Maudui were heard (to Golitsyn about stopping work and to Olenin about the issues raised in the comments on the project requiring priority consideration), his note and Montferrand's objections to it. It was decided to review the approved plans, facades and sections of the building and examine the building itself in the presence of Montferrand. The first inspection of the building took place on 15 August.

The essence of Maudui's remarks, which had a great resonance, boiled down to three main points: doubts about the strength of the foundation, the danger of uneven settlement of the building and the incorrect design of the dome, the size of which exceeded the allowable limits, and the possibility of the collapse of the dome, based on pylons of different construction times.

According to Maudui, Montferrand did not have the necessary qualifications and experience to work on such a serious project and, starting it, did not understand the difficulties involved in its implementation. Further, Maudui noted that, having started the restructuring of the building, Montferrand did not have a proper idea of ​​the existing foundations, did not know how deep new ones would need to be laid, and was going to make them from a rubble slab - in a way not suitable for such a complex structure. According to Montferrand's answer, he examined the foundations at the northern corner of the building, and also examined the cellars with one of the members of the commission. On the issue of driving a pile foundation under both porches of the newly constructed porticos, which, according to Maudui, was unnecessary and entailed "an unnecessary large expense", the committee considered the architect's actions correct.

According to Maudui, the four pylons on which the lantern with the dome of the third cathedral rested were “almost impossible” to leave, since the foundation under the “auxiliary supports” would not withstand the load of the existing pylons. Two old pylons and two newly built ones, according to Montferrand's plan, should serve as a support for a new lantern and dome. Maudui pointed out that pylons built at different times would have an uneven draft. The Committee considered that while maintaining the old foundations under the existing pylons, the construction of a heavy stone dome is not safe due to uneven settlement.

Having learned about the conclusions of the committee, Alexander I instructed him to fix the project, while observing the condition of "preserving, if possible, the existing walls, and even the old and new foundations." It was also ordered to preserve the main features of the Montferrand project - five domes and columned porticos. The decision of the interior space of the cathedral, the main dome, the illumination of the building was left to the discretion of the committee. Montferrand was allowed to participate in the work on a general basis. In addition to Montferrand itself, architects V.P. Stasov, A.I. Melnikov, A.A. Mikhailov Sr. and others participated in this competition.

As a result of the competition, the Committee could not make any decision: the projects were submitted for consideration to Alexander I. The latter, probably, realized that he had set an unsolvable task for the architects, and did not give any orders. There was a break in the work of the Committee, which lasted until February 1824, when a decree appeared on the continuation of design work. It again repeated the conditions of the emperor, the concession was the permission to change the elongated plan (proposed by Montferrand) to a square one, which gave some room for architects to work, but required the dismantling of part of the already built foundation. It was also allowed to dismantle the eastern pylons, which contributed to an increase in the space under the dome and the creation of a structurally correct connection between the drum and the dome. Thus began the second stage of the competition for the correction of the project, in which Montferrand himself took part. He studied the competition projects and revised his own, taking some solutions from the projects of Mikhailov 2nd and Stasov, and also proposed his ideas, correcting the mistakes of the previous project. The revised draft of Montferrand was provided to the emperor on March 9, 1825, and it was approved on April 8 of the same year.

 

1825 project

The new project of Montferrand, corrected and supplemented, was again recognized as the best and approved by Alexander I on April 13, 1825. The construction commission was reorganized - it included members of the abolished committee for reviewing Maudui's comments. The mistakes of previous years were taken into account: the construction of the cathedral was no longer carried out on a wide front, working drawings were developed (which had not been done before), calendar plans and estimates were drawn up (tentative, for a period of one year, the total cost of construction was never determined). In the new project, the main dome was enlarged, and four small belfries fixed the corners of the central square. The slight elongation of the basilica plan with three naves was skillfully disguised by four symmetrical porticoes. As a result, the temple acquired a more traditional five-domed view for Orthodoxy, but external symmetry was given at the cost of losing the protrusion of the altar apse in the eastern part. Montferrand took into account the advice and comments of the largest Russian architects, engineers, sculptors and artists. According to his new project, the cathedral was decorated with four columned porticos (in the project of 1818 there were only two of them - southern and northern). The central part of the cathedral was emphasized by a domed square formed by four new supporting pylons set wider than the others. Thanks to this, the main dome clearly fit into the square of the pylons and its sagging was excluded. Four bell towers were installed at the corners of the main volume, as if cut into the walls. Now they were located closer to the central dome than in the previous project. This further strengthened the square construction of the cathedral, its general appearance became more compact, balanced, the central dome began to dominate the composition. The symmetrical porticos made it possible to combine the artistically main northern façade, facing the Neva and the Bronze Horseman, and the main, according to the canons of the church, western façade, where the entrance to the temple is located. The northern and southern porticos with three rows of columns (in contrast to the single-row western and eastern ones) repeat, according to Montferrand's idea, in an enlarged size the portico of the Roman Pantheon (118-120 AD) as the most famous building of antiquity. By order of the President of the Academy of Arts, A. N. Olenin, who supported this idea, casts of capitals of the Pantheon's Corinthian order were ordered from Rome; they arrived in St. Petersburg in 1828.

 

Construction of the cathedral

Work on the construction of the foundation began in 1818, according to the first project of Montferrand. Difficult technical issues were to be solved by Betancourt, but, being employed in the construction of other facilities outside of St. Petersburg, he could not enter into all the problems that arose during construction [k 4]. Thus, Montferrand, who was not an engineer, who was initially entrusted with the author's control over the quality of materials and construction of works, was put in a difficult position. The scope of his duties did not include issues of supply and organization of construction work, and he sought from the Commission the expansion of powers and greater independence, by 1819 he succeeded [60].

Construction began with the dismantling of the existing semi-circular apses and preparatory work for the erection of new parts of the foundation. Montferrand emphasized that new foundations should be raised to the level of a granite base, thus ensuring a uniform settlement of the building. For the first year of construction, he requested 506,300 rubles, assuming that during the summer enough stone would be obtained to erect the facades of the building to the level of the entablature next year.

Under the new parts of the foundation, trenches were dug, from which water was pumped out. Then tarred pine piles 26-28 cm in diameter and 6.5 m long were driven vertically into the ground. The distance between the piles exactly corresponded to their diameter. Piles were driven into the ground with heavy cast-iron women using gates driven by horses. Ten blows were made on each pile. If after that the pile did not enter the ground, then it was cut off with the permission of the superintendent. After that, all the trenches were interconnected and filled with water. When the water froze, the piles were cut down to one level, calculated from the ice surface. According to Montferrand, 12,130 spruce piles were driven under the foundation.

When constructing the foundation, Montferrand used solid masonry, since he believed that “for the foundations of large buildings, solid masonry is preferable to any other type of its implementation, especially ... if the building is being built on flat and marshy ground ...” This also made it possible to connect the old Rinaldi foundation with the new one in the best way. and to a large extent guaranteed the building from the dangerous effects of precipitation.

The cutting of granite monoliths for the columns of the cathedral was carried out in the Pyuterlaks quarry near Vyborg. These lands belonged to the landowner von Exparre. The advantages of this particular place for the quarry were a large supply of granite, the proximity of the Gulf of Finland with a deep fairway and the postal route. Here is what Montferrand noted in his diary when he visited the quarry for the first time: “The surprise that we experienced when we saw ... granite rocks was, of course, great, but it was replaced by direct admiration when later we admired in the first quarry seven still unworked columns ... "

The work at the quarry was initially led by the merchant Samson Sukhanov, who also participated in the creation of the Rostral Columns and the Kazan Cathedral. Sukhanov, under an agreement dated January 1819, acted as a foreman, but already in May of the same year, part of the contract for the procurement of columns was transferred to the merchant Shikhin. Later, the contract was completely given to Shikhin. In September 1820, the first column for the cathedral was delivered to St. Petersburg.

The method of breaking out granite monoliths used in Püterlax was described in 1824 by Olenin, who visited the breaking together with Montferrand and Stasov. On a steep granite rock, there were monoliths of suitable size (at least 8 fathoms long and 1 or 2 wide, if two columns were supposed to be made from a monolith) without visible flaws. The layers of granite in Pyuterlax were separated by interlayers of earth (they were called rupases) about half an inch wide. The contour of the workpiece was marked, then holes were “drilled” along the width of the future column with iron drills with pointed ends (their length ranged from 3/4 to 2 fathoms). “Drilling” took place as follows: one worker held and turned the drill, the other two hit the drill with heavy sledgehammers until the workpiece was separated from the rock along the rupaz. Along the contour, marking the length of the future column, holes were drilled to a depth of rupaza, the distance between them was left at 5-6 inches. Gunpowder and wads were hammered into the holes and the monolith was separated along the length of the column by powder explosions. Further, iron wedges were driven “along the horizontal surface of the rock”, the workers beat them until the workpiece separated and fell onto the prepared scaffolding at the foot of the rock. Olenin noted that work on the separation of granite masses was difficult and slow.

The separated granite mass was examined for the absence of defects and compliance with the dimensions. Then the blank for the columns was given a rough "round shape" with the help of hammers. Transportation from the quarry was carried out on flat-bottomed ships, specially made for this at the Charles Byrd factory. The monoliths of the columns were rolled to the seashore, where they were loaded onto barges. Each ship was towed by two steamboats to the pier in St. Petersburg. There, the monoliths were unloaded and transported along a special rail track to the construction site for their final processing. The use of this rail track at the construction site was the first in Russia.

Frequently visiting the quarries, Montferrand noted: “Granite quarrying, labor of this kind in all other places is not very common, is encountered in Russia very often and is very well understood ... works that arouse our surprise at the works of antiquity are nothing more than a daily affair to which no one is surprised.

The pile driving, the foundations under the four towers, the east and west porticos, and the stylobates of the north and south porticos were completed in 1826. The next stage of construction was the erection of porticoes before the construction of the walls of the cathedral. This decision of the architect, contrary to common practice, was due to the complexity of installing granite columns.

Back in 1822, Betancourt designed scaffolding and mechanisms for lifting the columns of St. Isaac's Cathedral, they were not used by Montferrand, since construction work was suspended. According to the Betancourt project, a system of mechanisms was created, with the help of which Montferrand installed the Alexander Column on Palace Square in 1832. The drawings of the scaffolding were made for each portico separately, signed by Montferrand, as well as by the architects Glinka and Adamini, approved on June 15, 1828.

To lift the columns, special scaffolding was built, consisting of three high spans (for large porticos) or one span (for small ones), formed by vertical posts covered with beams. 16 cast-iron capstan gates were installed aside, each of which employed eight people. The column was sheathed with felt and mats, tied with ship ropes and rolled into one of the spans of scaffolding, and the ends of the ropes were fixed on capstans through a system of blocks. The workers, rotating the gate, brought the monolith to a vertical position. The installation of one 17-meter column with a diameter of 1.8 meters and a mass of 114 tons took about 40-45 minutes. Montferrand noted in his notes that "the wooden construction of the scaffolding ... is so perfect that with all forty-eight installations of the columns, even a simple creak was never heard."

The first column (on the far right in the northern portico) was installed on March 20, 1828 in the presence of the royal family, foreign guests, many architects who had come specially for this celebration, and ordinary citizens who filled the square and the roofs of the surrounding houses. A platinum medal with the image of Alexander I was laid under the base of the column. The construction of the porticos was completed by the autumn of 1830.

Then the construction of the supporting pylons and walls of the cathedral began. For greater strength, granite gaskets and metal ties of various profiles were made into the brickwork on lime mortar for greater strength. Walls and pylons were laid out simultaneously around the entire perimeter. Montferrand's decision to lay pylons in alternating rows of brick and hewn granite was innovative, according to Rotach and Chekanova, thus creating an "ideal supporting structure". Granite pads of varying plan configurations ensured pressure transfer across cleanly hewn horizontal and vertical surfaces.

The thickness of the walls ranged from 2.5 to 5 m. The thickness of the outer marble cladding was 40-50 cm, the inner one - 15-20 cm. It was carried out simultaneously with the brickwork, using iron hooks (pyrons) inserted into holes specially drilled for this . For the roofing, wrought iron rafters were made. Ventilation galleries were arranged inside the southern and northern walls. For natural lighting of the cathedral, light galleries were made above the galleries of the attic.

In 1836, the construction of walls and pylons was completed and the construction of ceilings began. The built brick vaults are 1.1 to 1.25 m thick and rest on six pylons. In addition to constructive brick vaults, decorative ones were also made, which were an iron frame covered with a metal mesh and lined with artificial marble. A space 30 cm high was left between the decorative and structural vaults. Such a double overlap of the vaults is a characteristic feature of the cathedral, which has not been seen before in other church buildings in Russia and Western Europe.

In 1837, when the base of the dome was completed, the installation of 24 upper columns began. The columns climbed upward along an inclined flooring - a system of flying buttresses, which relied on the base of the colonnade on one side, on the walls and pylons on the other. The lifting was carried out with the help of special carts. To turn the columns, devices were used from two cast-iron circles, balls were inserted into the groove of the lower one.

The next step in the construction of the cathedral was the construction of the dome. Montferrand sought to lighten the dome as much as possible without losing strength. To do this, he proposed to make it not brick, as was envisaged by the 1825 project, but completely metal. The calculations for the dome were made by engineer P.K. Lomnovsky. Casting of metal structures of the dome was carried out at the factory of Charles Byrd. In this case, 490 tons of iron, 990 tons of cast iron, 49 tons of copper and 30 tons of bronze were used. The dome of St. Isaac's Cathedral became the third dome in the world, made using metal structures and shells (after the tower of the Nevyansk plant in the Urals, built in 1725, and the dome of the Mainz Cathedral - in 1828). The model was the dome of London's St Paul's Cathedral, designed by Christopher Wren. But Montferrand, having borrowed the design, made it from other materials.

Structurally, the dome consists of three interconnected parts formed by cast-iron ribs: the lower spherical, the middle - conical and the outer - parabolic. The metal frame is made up of 24 I-section ribs. The strip connecting the shelves of the I-beam is perforated. The connections of the frame parts were made on bolts. The diameter of the outer vault is 25.8 m, the lower one is 22.15 m. The space between the trusses for insulation was filled with hollow conical pottery pots on brick lintels with filling the gaps between them with lime with crushed stone. It took about 100,000 of these pots to complete the vaults. Pot vaults improve the acoustics of the temple and are much lighter than brick ones, but, as Nikitin notes, the dome does not protect from freezing.

The thermal insulation of the pot vaults was made of felt and cow's wool filled with resin and harpius (pine rosin). The felt, in turn, was covered with lime-sand mortar, which was painted with oil paint. The exposed parts of the metal structures were also protected with felt. The inner conical dome is covered with bluish-tinted copper sheets, with large bronze rays and stars, creating a spectacular picture of the night sky. Outside, the dome is covered with gilded copper sheets tightly fitted to each other.

The gilding of the domes of the cathedral in 1838-1841 was carried out by fire gilding. In the process, they were poisoned by mercury vapor and 60 craftsmen died. According to contemporaries, from 60 to 120 people (probably, they meant not only the gilding of the dome, but also the gilding of interior details) died from mercury poisoning during the construction of the cathedral. Subsequently, the gilding of not very large parts was carried out by a safe method of electroplating. In total, 400,000 workers - state and serfs - took part in the construction of the cathedral. Judging by the documents of that time, about a quarter of them died from diseases or died as a result of accidents. The total construction costs amounted to over 23 million silver rubles. By 1842, the building of the cathedral was basically completed, work began on the design, which lasted sixteen years.

Montferrand's contemporaries explained the long period of construction of the cathedral (40 years) by the fact that a certain soothsayer predicted the death of the architect immediately after the construction of St. Isaac's Cathedral was completed. Therefore, the architect was in no hurry with the construction. Montferrand really lived a little less than a month after the consecration of the cathedral.

 

Cathedral interior design projects. Klenze and Montferrand

In the process of designing the interior decoration of the cathedral, Montferrand made three trips to Western Europe to study different types of temple interiors on the spot (the first time he was in Italy in 1806 as part of the Napoleonic army). In 1842, as an architect of Russia, he visited Florence and Rome, carefully studied St. Peter's Basilica in the Vatican. In 1845 he was in Carrara, Genoa and again in Florence and Rome. In 1851 - in Carrara, where he oversaw the manufacture of marble details for St. Isaac's Cathedral. The eclectic thinking of the new era of historicism was also manifested in Montferrand's "Architectural, artistic and historical description of St. Isaac's Cathedral", in which he tried to recreate the history of the architecture of Christian churches and present his project as the most complete, having absorbed all previous achievements. However, even earlier, the emperor probably had doubts about Montferrand's ability to create a representative project for the design of the interior of the cathedral. When Leo von Klenze visited St. Petersburg in 1839 in connection with an order to design the building of the New Hermitage, Emperor Nicholas I instructed him to draw up his design for the decoration of St. Isaac's Cathedral. Klenze criticized Montferrand's project and, in particular, proposed encaustic painting to be entrusted to the German painter P. von Cornelius, the installation of a stained-glass window in the altar, and even constructive changes in the already built cathedral. There was a conflict. Montferrand sent out indignant letters[89]. During a trip abroad in 1842, Montferrand, in addition to Italy, visited London and Paris (for the sake of studying the interiors of St. Paul's Cathedral and the Church of St. Genevieve). On the way back, he went to Munich, met with Klenze and managed to convince him of the advantages of his own project. Emperor Nicholas I agreed with the proposals of Montferrand, and only the stained-glass window of the altar part depicting the resurrected Savior was realized from the Klenze project.

 

Finishing work

Work on the interior design began in 1841, with the participation of famous artists (Fyodor Bruni, Karl Bryullov, Johann Konrad (Kondrat) Dorner, Ivan Burukhin, Vasily Shebuev, Franz Riess) and sculptors (Ivan Vitali, Pyotr Klodt, Nikolai Pimenov) . The management of the paintings was entrusted to the rector of the St. Petersburg Academy of Arts, Professor V. K. Shebuev, the decor project and the general concept of the murals were developed by Montferrand, considered by the Synod and approved by the emperor.

One of the main problems was the choice of technique for the execution of picturesque panels. According to the initial proposal of Klenze (Nicholas I agreed with him), the frescoes of the cathedral were to be made using the encaustic technique. However, Bruni, who was involved in the discussion of the method of performing future murals, after consultations with Klenze, held at the beginning of 1842 in Munich, made a report in which he indicated that this painting technique was completely unsuitable for the climatic conditions of St. Petersburg. Based on the opinion of the restorer Valati, Bruni spoke in favor of oil painting on canvas, framed in copper frames with a bottom. Montferrand also leaned in favor of oil painting. Bruni was commissioned to make a sample of encaustic painting on copper, but soon it was decided to paint the walls of the cathedral with oil paints on a special primer, and to perform the image in oil on bronze boards.

At the same time, at the prompting of Montferrand, P. Krivtsov compiled a report on the desirability of establishing a Russian mosaic production, which was not supported by the Academy of Arts. However, on August 12, 1845, Nicholas I "ordered to stop writing icons for St. Isaac's Cathedral on copper boards that were difficult to manufacture, ordered to paint on canvas and decided" to establish a mosaic institution for the image after these icons in mosaic "".

According to the distribution of works, Bryullov was supposed to paint the main dome (the largest composition with an area of ​​800 square meters) and sails in the central nave, Bruni - the duct vault and the attic of the main nave, Dorner - 12 icons containing 28 images for the side parts of the large iconostasis, Basin - aisles of Alexander Nevsky and St. Catherine. The western part of the cathedral was reserved for stories on themes from the Old Testament, the eastern part - for episodes from the life of Christ. Six paintings were painted by the Italian painter Cesare Mussini.

The high humidity in the cathedral precluded the creation of soil resistant to adverse external influences. The wall was plastered for painting, cleaned with pumice, heated with braziers to 100-120 degrees and several layers of mastic were applied to it. The low quality of the basis for painting was the reason that in some cases it had to be removed, and the artists repainted the paintings. In some places, the soil lagged behind the plaster. In his letter dated December 24, 1849, Bruni noted that painting on fresh soils was impossible because of the “nitrate oxide” subsequently protruding onto the surface of the painting from the wall. A stable composition was created only in 1855, three years before the completion of paintings in the cathedral.

Since in the cathedral, due to temperature differences, high humidity and lack of ventilation, there were unfavorable conditions for preserving the murals in their original form, when decorating the interior from 1851, it was decided (Emperor Nicholas I insisted on this) to use mosaics for interior decoration. Smalt for St. Isaac's Cathedral was made in the mosaic workshop of the Academy of Arts; On December 7, 1864, on the 3rd line of Vasilyevsky Island, in a special building, an institution appeared, later called the "Imperial Mosaic Institution", which was headed by Yu. P. Bonafede. Mosaic icons for St. Isaac's Cathedral at that time were created by its workers: M. A. Khmelevsky, Academician N. M. Alekseev, I. D. Burukhin, M. P. Shchetinin, G. M. Agafonov, F. F. Gartung, A N. Frolov, N. M. Golubtsov, M. P. Muravyov, P. S. Vasiliev, V. A. Kolosov, E. G. Solntsev, and I. S. Shapovalov.

The creation of mosaic panels continued until the outbreak of the First World War. When creating sixty-two mosaics of the cathedral, more than 12 thousand shades of smalt were used, the backgrounds were made of golden smalt (cantorels). Mosaic images were made from originals by T. A. Neff.

The painting by S. A. Zhivago “The Last Supper”, the painting of the sails of the main dome, the attic (“The Kiss of Judas”, “Behold the Man”, “The Scourging”, “Carrying the Cross” by Basin) and pylons were replaced with mosaics. The mosaic paintings of the cathedral were exhibited at the London World Exhibition of 1862, where they were highly appreciated.

A new tomb was made for the temple. The tomb of the Church of the Savior on Sennaya was taken as a model (the author is the jeweler Fyodor Verkhovtsev).

At the suggestion of Leo Klenze, a stained-glass window was included in the interior of the cathedral - an element of the decor of Catholic churches. The image of the Resurrected Savior in the window of the main altar was approved by the Holy Synod and personally by the emperor. The German artist Heinrich Maria von Hess worked on his sketch, made under the direction of Max Einmiller, head of the Glass Painting Establishment at the Royal Porcelain Manufactory in Munich. In the window of the main altar, a stained-glass window was installed in 1844 for demonstration to Nicholas I, and was soon dismantled, judging by documentary references; in 1847 he again took his place in the window.

 

Sculptural decoration of the facade

The project of monumental and sculptural decoration of the exterior (four bas-reliefs on the pediments and sculpture at their corners, sculpture of the attic and balustrades of the dome, bas-reliefs of doors in the niches of the porticos) was developed by Montferrand in 1839. The visual program was proposed by Olenin already in 1834, it was implemented with some changes. Remaining entirely in the scheme determined by the principles of the Empire style, the external decor of the cathedral is made not only in the Empire style, but also in Baroque and Renaissance forms, reflecting the transitional period when the classicist settings no longer satisfied the artists, and they were replaced by new decorative and plastic principles.

Olenin and the sculptor P. Svintsov proposed to involve domestic masters to work on the outdoor sculptural decoration. However, at the request of Nicholas I, two pediments (northern and eastern porticos) were made by the French sculptor Lemaire. His work, according to contemporaries, and later researchers, was not very successful, two bas-reliefs of other porticos were made by I. Vitali, whose works Montferrand accidentally saw during his trip to Moscow. The pediments of the porticoes were cast at Byrd's factory in 1840-1845. The statues of the 12 apostles (Vitali) crowning the pediments - three of them - for the northern portico - were made by the electroforming method at the Duke of Leuchtenberg's factory.

The balustrade of the dome is decorated with twenty-four statues of angels (I. Herman, 1839-1840), holding various symbols and attributes. Castings from ancient statues from the Academy of Arts served as models for their figures.

The outer doors of the cathedral (the project of Montferrand, approved in 1840, created under the influence of the gates of L. Ghiberti for the Florentine Baptistery of San Giovanni) were entrusted under the contract of 1845 to I. Vitali (sculptors R. K. Zaleman and A. N. Belyaeva helped). Made at the request of Emperor Nicholas I by galvanoplastic method, the process management (at the plant of the Duke of Leuchtenberg) was entrusted to the inventor of the method, Academician B. Jacobi.

 

Construction cost

The total cost of building the cathedral from 1818 until the completion of work in 1864 amounted to 23.26 million silver rubles. Of these, the cost of building the foundation amounted to 2539 thousand rubles in banknotes, the cost of 48 granite columns of the porticos, taking into account their installation, was 2612 thousand rubles in banknotes, the laying of walls - 2505 thousand rubles in banknotes, their facing with marble - another 7485 thousand rubles in banknotes, the cost of building four pediments of the porticos is 2278 thousand rubles in banknotes, roofs - 2445 thousand rubles in banknotes.

 

Consecration

The solemn consecration of the cathedral took place in 1858, on May 30, on the day of memory of St. Isaac of Dalmatia, in the presence of Emperor Alexander II and members of the imperial family. The troops were lined up, whom the emperor welcomed before the start of the rite of consecration, which was headed by Metropolitan Grigory (Postnikov) of Novgorod and St. Petersburg. Tribunes for the people were set up on Petrovsky and St. Isaac's Squares; the neighboring streets and the roofs of the nearest houses were crowded with people.

In connection with the construction and consecration of the cathedral by Alexander II, a state award was established - the medal "In memory of the consecration of St. Isaac's Cathedral." It was awarded to persons who took part in the construction, decoration and consecration of the cathedral.

 

In the 19th century

6 years after the consecration of the cathedral and upon completion of the work of the construction commission, in 1864, the cathedral building was transferred to the Ministry of Communications and Public Buildings. At the cathedral, the positions of inspector and architect were established, and also, for constant monitoring of the state of the cathedral, a special “technical and artistic meeting” was created from three professors of the Academy of Arts.

In 1871 St. Isaac's Cathedral was transferred under the control of the Ministry of the Interior.

In 1879, John Polisadov founded the Society of Preachers for the pulpit of St. Isaac's Cathedral - the first society of its kind in the capital.

In 1883, the status of St. Isaac's Cathedral changed: the cathedral (like the Cathedral of Christ the Savior in Moscow) passed into dual subordination, to the department of the Orthodox confession in the "economic sense", and remained under the jurisdiction of the Ministry of Internal Affairs in the "technical and artistic" sense.

At the same time, the issue was discussed in order to transfer the cathedral building to the sole management of the spiritual department. The metropolitans of both capitals agreed, but the rector of the Academy of Arts Alexander Rezanov opposed, saying that he would not allow a situation where the building, which cost 15 million rubles and 45 years of work, was left without the supervision of specialists and "large material support from the government." Rezanov's arguments were taken into account, and both cathedrals in the "technical and artistic" respect remained under the jurisdiction of the Ministry of Internal Affairs. On May 25, 1883, Emperor Alexander III approved the “opinion of the State Council” on two cathedrals, in the third part of the Complete Collection of Laws of the Russian Empire, this document is numbered 1600 and is called “On the Procedure for Managing St. Isaac’s Cathedral in St. Petersburg and Christ the Savior in Moscow ".

 

In the 20th century

At the beginning of the 20th century, the question arose again of transferring St. Isaac's Cathedral (and the Cathedral of Christ the Savior) to the undivided control of the department of the Orthodox confession. The need for such a change was motivated as follows: difficulties in managing buildings due to their dual subordination - to the Ministry of Internal Affairs and the spiritual department. On October 28, 1908, this issue was considered at a meeting of the Council of Ministers, and the status of the cathedrals again remained unchanged - dual subordination. In addition, to find out the necessary repairs to the buildings, commissions were formed, which included representatives of four ministries - internal affairs, finance, the department of the Orthodox faith and state control.

Based on the decree on the separation of church and state, the cathedral building and church property were nationalized. In 1918, the building came under the jurisdiction of the People's Commissariat of Property of the Republic, and already in December 1919 it was transferred to the use of the parishioners of the cathedral. On the part of the parishioners, more than 30 people signed the agreement, according to its condition, the parish used the cathedral free of charge, but was obliged to ensure the payment of expenses for the current maintenance of the building (heating, repairs, security, etc.). In May 1922, during the seizure of church valuables, 48 kg of gold items and more than 2 tons of silver jewelry were seized from the cathedral. On April 29, 1922, its rector, Archpriest Leonid Bogoyavlensky, was arrested. In March 1923, the cathedral came under the control of the parishioners of the Russian Orthodox Church (Renovationists). The agreement on the use of the cathedral with a public organization (parish) was terminated due to the improper performance of their duties; services were terminated when the Presidium of the All-Russian Central Executive Committee on June 18, 1928 decided "to leave the cathedral building in the exclusive use of Glavnauka as a museum monument." The remaining property of the temple was sold through the State Fund, and all the bells were removed and melted down.

On April 12, 1931, one of the first anti-religious museums in Soviet Russia was opened in the cathedral.

During the Great Patriotic War, the cathedral suffered from bombing, shelling, cold and dampness; on the walls and columns in some places there are traces of shells. During the siege, exhibits from museums from the suburbs of Leningrad, as well as the Museum of the History of the City and the Summer Palace of Peter I were kept in the cathedral.

Since 1948, it has been functioning as the St. Isaac's Cathedral Museum. Restoration work was carried out in the 1950s and 1960s. An observation deck is arranged on the dome, from where a panorama of the central part of the city opens.

From 1931 to 1986, the Foucault pendulum functioned inside the temple, which, thanks to the length of the thread of 98 m, clearly demonstrated the rotation of the Earth. Currently, the pendulum has been dismantled and stored in the basement of the cathedral.

In 1990, church services were resumed, currently (2017) they are held daily.

On September 3, 1991, the State Bank of the USSR issued a 50-ruble commemorative coin with the image of St. Isaac's Cathedral in the series "500th Anniversary of the United Russian State". The coin is made of 999 gold with a circulation of 25,000 pieces and weighs 7.78 g.

The cathedral was under the jurisdiction of the State Museum-monument "St. Isaac's Cathedral".

From 1968 to 2002 Georgy Butikov was the director of the museum.

 

In the 21st century

The cathedral is under the jurisdiction of the State Museum-monument "St. Isaac's Cathedral".

From 2002 until January 2008, the director of the museum was Nikolai Nagorsky, from June 3, 2008 - Nikolai Burov (former head of the St. Petersburg Committee for Culture).

In 2012, the reconstruction of the bells, destroyed around 1930, began. The first bell weighing about 10 tons was cast in 2012. In 2013, 14 bells were made in Voronezh and brought to St. Petersburg, intended for the southeastern bell tower. In 2015, Bishop Markell of Tsarskoye Selo consecrated the last 16th bell of the updated scale weighing about 17 tons - the bell was installed on the northwestern bell tower of the cathedral. During the procession, all 16 bells installed on three bell towers of the cathedral are used.

On June 15, 2017, Yuri Vitalyevich Mudrov was appointed director of the museum.

In 2018, St. Isaac's Cathedral was chosen as the Orthodox symbol of St. Petersburg by voting results.

 

The question of the transfer of the cathedral to the Russian Orthodox Church

In 2015, the issue of transferring St. Isaac's Cathedral under the control of the Russian Orthodox Church (ROC) was raised for the third time; in mid-July 2015, Metropolitan Varsonofy appealed to the city authorities with a request to transfer the cathedral to the diocese, but was refused. Officials referred to the fact that in the event of the transfer of the cathedral-museum to the Russian Orthodox Church, the costs of its maintenance will fall on the shoulders of the state. On March 28, 2016, Orthodox activists filed a lawsuit in connection with the refusal to transfer the cathedral to the Russian Orthodox Church. In April 2016, Metropolitan Varsonofy addressed the Chairman of the Government of Russia Dmitry Medvedev with a repeated request to transfer St. Isaac's Cathedral, the Savior on Spilled Blood and the building of the Smolny Monastery to the Russian Orthodox Church. On January 10, 2017, the governor of St. Petersburg, Georgy Poltavchenko, announced that the issue of transferring St. Isaac's Cathedral to the use of the Russian Orthodox Church had been resolved, but the building would fully retain its museum and educational function.

The St. Petersburg Union of Museum Workers regarded the transfer of the cathedral to the Russian Orthodox Church as the liquidation of the museum. Museum director Nikolai Burov said that as a result of the transfer of the cathedral, about 160 museum employees may lose their work.

On January 28, 2017, an uncoordinated rally of citizens against the transfer of the cathedral to the Russian Orthodox Church took place on the Field of Mars in St. Petersburg, and at the same time, an action of citizens agreed with the mayor's office - supporters of the transfer of the cathedral. According to various sources, from 1,500 to 5,000 people took part in the action against the transfer of the cathedral, and several dozen people took part in the action of supporters of the transfer of the cathedral.

On February 12, 2017, after a meeting with deputies of the city Legislative Assembly, the townspeople surrounded the cathedral with two living rings of the protesters, the press called this action the "Blue Ring".

On February 19, 2017, a religious procession took place, which brought together up to 8 thousand citizens who support the transfer of St. Isaac's Cathedral to the Russian Orthodox Church. The procession was attended by priests, youth from parishes of the St. Petersburg Metropolis, students of the Theological Academy and other universities, members of Cossack organizations, Orthodox activists, parishioners of city churches, bikers from the Night Wolves motorcycle club, fans of the Zenit football club.

On March 13, 2017, the Smolninsky District Court of St. Petersburg decided to bring the Russian Orthodox Church and the Ministry of Culture as defendants in a lawsuit filed by a group of citizens (Boris Vishnevsky and others) against the Property Relations Committee of St. Petersburg regarding the use of St. Isaac's Cathedral. On March 16, the Smolninsky court dismissed the case.

On March 14, 2017, Vice Governor Vladimir Kirillov announced that on that day the administration of St. Petersburg had not received an official request from the Russian Orthodox Church to transfer St. Isaac's Cathedral for free use. On May 3, 2017, Governor Georgy Poltavchenko confirmed that the Government of St. Petersburg had not received an application from the Russian Orthodox Church to transfer the building of St. Isaac's Cathedral for use.

On October 5, 2017, an audit of the Department of Economic Security and Anti-Corruption of the Main Directorate of the Ministry of Internal Affairs of Russia for St. Petersburg and the Leningrad Region on facts of corruption and abuse by the museum management, initiated by the State Duma of the Russian Federation, began.

On December 7, 2018, Metropolitan Varsonofy consecrated the chapel of St. Catherine (before that, liturgies were celebrated only in the chapel of Alexander Nevsky, and on holidays - on the main throne).

On December 30, 2018, the order on the transfer of St. Isaac's Cathedral to the use of the Russian Orthodox Church for 49 years, which was given on December 30, 2016, became invalid. The agreement with the Russian Orthodox Church was supposed to be concluded within two years from the date of issuance of the order, but the spiritual department has not yet sent an official application. On March 29, 2019, RBC, citing an unnamed source in the government and an interlocutor close to the Ministry of Culture, published information that "the issue of transferring St. Isaac's Cathedral to the Russian Orthodox Church is no longer on the agenda." Later, the press service of the government drew the attention of journalists that St. Isaac's Cathedral is the property of St. Petersburg, and not federal property.

In 2022, a decision was made to restore the murals “Saint Alexander Nevsky praying before the cross for the liberation of the Fatherland”, “Victory of St. Alexander Nevsky over the Swedes”, “Christian death of St. Alexander Nevsky” and “Transfer of the relics of St. Alexander Nevsky from Vladimir to St. Petersburg in 1724".

 

Cathedral building

Height - 101.5 m, internal area - more than 4000 m².

 

Appearance

St. Isaac's Cathedral is an outstanding example of late classicism, also called the latest building in this style, in which new trends are already emerging (neo-Renaissance, Byzantine style, eclecticism).

The temple is five-domed with a dominating central hemispherical dome and four small domes ending with square bell towers. The belfries are located in 4 small domes on the sides of the large one (in the 19th century, 11 bells were cast for the temple by the Valdai master I. M. Stukolkin, the largest of them weighed about 29 tons). The large dome is crowned with an octagonal lantern. The facades are decorated with porticos of the Corinthian order - from the north and south, more solemn, sixteen-column, overlooking the square, from the east and west - eight-column porticos. The main entrance, in violation of custom, is located in the western portico, and has no eastern entrance. Triangular pediments are decorated with sculptural groups. The building is rectangular in plan, taking into account the porticoes, its outline is an almost equal-ended cross. The cathedral stands on a plinth, a stereobath with two wide steps. Only five domes and a central layout connect the building with the tradition of Orthodox architecture.

The height of the cathedral is 101.5 m, length (including porticos) 111.3 m, width - 97.6. The outer diameter of the dome is 25.8 m, the inner diameter is 21.8 m. The building is decorated with 112 monolithic granite columns of various sizes. The walls are lined with light gray Ruskeala marble, part of the facing slabs, cracked due to uneven settlement of the building, were replaced during restoration work in the 1870-1890s with bardillio marble.

The cathedral is the tallest building of the architectural complex, which includes four squares of the city (Admiralty, Palace, St. Isaac's and Senate) and facing the Neva in the north. The axis of the building, located in the depths of St. Isaac's Square, in the north-south direction coincides with the axis of the square. On the north side of Isaac there is the Alexander Garden, and on the opposite, south side, there is a square, which was laid out immediately after the construction of the cathedral was completed. Due to its position, the cathedral is perfectly visible from all sides; in the distance, some disproportion of the building and the massiveness of the sculptural decoration are hidden. The best view (according to Nikitin) of Isaac opens from the University embankment on Vasilyevsky Island. The cathedral rises framed by the facade of the Admiralty with a boulevard (left) and the buildings of the Senate and Synod with an arch (right). Isaac serves as a backdrop for the monument to Peter I, the panorama is limited at the bottom of the Neva embankment, and the bell towers and the golden dome are reflected in its waters. With its monumental forms and richness of decoration, the cathedral rises above the buildings of the square and even "suppresses with its architectural power."

 

Sculpture

More than 350 sculptures adorn the outside of the cathedral building, the leading theme of the sculptural complex is the glorification of Jesus Christ, scenes from his earthly life and the Passion of the Lord. The creators of the monumental decor (sculptors Vitali, Klodt, Lemaire, Loganovsky) managed to achieve harmonious unity with the scale and architectural forms of the building.

 

North facade

The phrase placed in the frieze of the northern portico - "Lord, by your power the king will rejoice" - can be considered an expression of the idea of \u200b\u200bthe whole building.

The relief of the pediment of the northern portico is the "Resurrection of Christ" (1839-1843, sculptor F. Lemaire). In the center of the composition is Christ rising from the tomb, to the right and left of him are angels, and behind them are frightened guards and shocked women. On holidays, high gas lamps were lit in the corners of the cathedral, above the attic, supported by kneeling angels (sculptor I.P. Vitali). These sculptures link the lower part of the cathedral with the dome rising above it.

Statues crowning the pediments: The Apostle Peter (left) is depicted with the keys to the gates of the kingdom of heaven. Apostle Paul (right) with a sword, a symbol of his zealous service to Jesus Christ. Evangelist John (in the center) is depicted with an eagle - a symbol of the high soaring of his theological thought. The sculptures in the niches - "Carrying the Cross" (left niche) and "The Entombment" (right niche) - were made by the sculptor P. K. Klodt.

Doors: (sculptor Vitali) "Entrance to Jerusalem", "Behold the Man", "Flagellation of Christ", St. Nicholas the Wonderworker, St. Isaac of Dalmatia, kneeling angels.

 

Western facade

On the pediment of the western portico there is a bas-relief "The Meeting of Isaac of Dalmatia with Emperor Theodosius", made in 1842-1845 by the sculptor I.P. Vitali. Its plot is the unity of two branches of power - royal and spiritual (it is no coincidence that the portico is turned towards the Senate and the Synod). Depicted in the center of the bas-relief, Isaac of Dalmatia with a cross in his left hand, the other seems to bless Theodosius, who bowed his head, dressed in armor. To the left of the emperor is his wife Flacilla. The imperial couple was associated with Nicholas I and Alexandra Feodorovna, but these two characters were not given a portrait resemblance. More to the left are two figures, the first of which resembles the president of the Academy of Arts A. N. Olenin, and the second - with the minister of the imperial court and chairman of the Commission for the construction of the cathedral, Prince P. M. Volkonsky. On the right side are kneeling warriors. In the left corner of the bas-relief is a small half-naked figure with a model of the cathedral in his hands - a portrait of the author of the project of St. Isaac's Cathedral, O. Montferrand. The inscription on the frieze is "To the King of Kings".

Thomas (sculptor Vitali) - this apostle is depicted with a square in his left hand (as an architect), with his right hand stretched forward, with a surprised expression on his face. He was prone to lack of faith and believed in the resurrection of Christ only when he touched him. Bartholomew (sculptor Vitali) - depicted with a cross and a scraper. Mark (sculptor Vitali) - the evangelist is depicted with a lion, symbolizing wisdom and courage.

Door: sculptor Vitali: "The Sermon on the Mount", "The Resurrection of Lazarus", "The Healing of the Paralytic", Apostle Peter, Apostle Paul, Kneeling Angels.

 

South facade

On the pediment of the southern portico there is a bas-relief "The Adoration of the Magi" made in 1839-1844 by the sculptor Vitali. In the center is depicted Mary with a baby sitting on a throne. She is surrounded by the magi who came to worship, among them the figures of the Mesopotamian and Ethiopian kings stand out. To the right of Mary, with his head bowed, stands Joseph. On the left side is an old man with a child, in the hands of the child is a small casket with offerings. In the figures of an old man with a child, Mesopotamian and Ethiopian kings, an Ethiopian slave, individual features are visible; there is evidence that they were modeled from sitters. The inscription on the frieze - "My temple will be called the temple of prayer." Andrei (sculptor Vitali) - in Russia, he is considered the patron saint of the fleet. Philip (sculptor Vitali). Matthew (sculptor Vitali) - the evangelist is depicted at the time of work, with an angel behind his back, a symbol of the purity of deeds and thoughts.

East facade

On the bas-relief of the eastern portico facing Nevsky Prospekt: "Isaac of Dalmatia stops Emperor Valens" (1841-1845, sculptor Lemaire). In the center of the bas-relief - Isaac of Dalmatia blocks the path of Emperor Valens, predicting his imminent death, an experienced warrior who reigned before Theodosius was the patron of the Arians, whose teaching was an attempt to revise the Christian teaching. Isaac of Dalmatia, a follower of Christians, was imprisoned (the bas-relief depicts the moment when soldiers fetter his hands with chains), and only Theodosius, a follower of Christian teaching, freed him. The inscription on the frieze: "In thee, Lord, we hope, let us not be put to shame forever."

Jacob (sculptor Vitali) is the brother of the Evangelist John. Simon (sculptor Vitali) - depicted with a saw. This apostle enlightened Africa with the teachings of Christ, according to another legend, the British Isles, Babylonia, Persia, and was crucified on the cross. The saw is a symbol of the torment that all the apostles had to experience.

Luke (sculptor Vitali) - the evangelist is depicted with a calf, symbolizing the holiness of the covenant. He preached in Libya, Egypt, Macedonia, Italy and Greece and, according to one version, died peacefully at the age of 80; according to another, he was martyred and, for lack of a cross, was hanged on an olive tree.

 

Colonnade

At a height of 43 meters above the ground around the drum of the dome, there is a colonnade consisting of 24 columns, 14 meters long and weighing up to 67 tons. The drum has 12 giant windows. Two spiral staircases of 200 steps lead to the colonnade and a beautiful panorama of the city opens from there. The entrance to the colonnade is from the south side of the cathedral, and the exit is from the north.

 

Interior

The building of the cathedral is of the cross-domed type. There are three altars in the cathedral; Its interior space, divided into three naves, does not give the impression of integrity - it is created not by architectural means, but by decorative design. In the project of interior decoration, Montferrand assigned the main place not to continuous wall painting, as was customary in Orthodox churches, but to the decoration of large surfaces with marble of various colors. Thus, the viewer's attention should have been focused on the paintings of the ceiling of the dome, the sails of the vaults. The interior design combined Byzantine, Renaissance, Baroque and modern Western European (Italian and French) traditions.

The walls are lined with white Italian marble, the bottom of the walls - with black slate, the columns and pilasters - with light pink and cherry Tivdia. Marbles of saturated colors (green, red, yellow, bright red with white inclusions), Solomenskaya breccia were also used in the interior decor. The floor is lined with slabs of light and dark gray Ruskeala marble, as well as pink and cherry red Tivdi marble. The carved iconostasis is made of white marble, finished with malachite and Badakhshan lapis lazuli. Its lower part is lined with Shoksha quartz, the steps leading to the altar are made of the same material.

The sculptural decoration of the interior plays a key role in creating an artistic image and semantic unity, as in a Catholic church. However, unlike the Catholic church, where the traditional artistic and plastic decoration took shape over the centuries, the sculptural complex of the interior of Isaac did not form an integral ensemble, it was created under the influence of several styles and falls into several groups with different artistic value. The decoration of the drum of the main dome, decided in the spirit of the Italian Renaissance, is recognized by art historians as the most successful. Twelve caryatid angels with elongated proportions of figures emphasize the vertical division of the drum, between them are placed paintings with images of the apostles. Using the same type, Vitali, constantly changing it, giving the figures dynamic poses, managed to avoid monotony. The sculptural decoration of the vaults (here the works of the Italian Baroque served as a model), despite the high skill of execution, did not turn out so organic: its connection with the internal architecture is very weak. Massive sculpture, complemented by a complex empire-style ornament, coupled with chandeliers visually lowers the vaults.

The sculptural decoration of the three internal doors of the cathedral according to the drawings of Montferrand was performed by Vitali and R. Zaleman. Moreover, Vitali deviated from tradition and gave the images of saints characteristic portrait features, reminiscent of sketches of workers that the sculptor made at a construction site.

A stained-glass window was introduced into the interior of an Orthodox church - originally an element of decoration of Catholic churches. Its area is 28.5 square meters, the height is 9.5 meters, the parts are fastened with lead solders. The image of the Resurrection of Christ is a key monument in the history of stained glass art in Russia. The appearance of a glass picture in the cathedral church of the capital was the result of the interaction of Western and Eastern Christian traditions, a kind of synthesis of a figurative Catholic stained-glass window and an altar Orthodox icon. The appearance of a stained-glass window in the main church of Russia introduced this type of monumental art into the design system of the country's Orthodox churches. The image of the Resurrected Savior on the altar window of St. Isaac's Cathedral has become an iconographic model for many stained-glass windows in Russian churches, both in the 19th century and in our time.

St. Isaac's Cathedral presents a unique collection of monumental paintings of the first half of the 19th century - 150 panels and paintings.

 

Estimates by contemporaries. Research. Art Criticism

The works devoted to the cathedral and published until the end of the 19th century, basically only described the history of the cathedral, its design and construction, and the shrines stored in it. There was no art criticism as such at that time. Usually, the authors noted one drawback of the building - its insufficient illumination (especially in the northern and southwestern parts), due to which it was impossible to see the painting of the upper tiers. In a separate body of publications, St. Isaac's Cathedral is considered only as a religious building. Among them - a series produced by the headman of the cathedral Bogdanovich "Chair of St. Isaac's Cathedral", books by Archpriest Smirnov and others. The theme of the merger of the two authorities, secular and ecclesiastical, the embodiment of which was the temple, is carried out in the works "The Reign of Nicholas I" and A.P. Uzanov.

The art history analysis of the structure began in the second half of the 19th century. In 1865, a description of St. Isaac's Cathedral with drawings and plans was published, compiled according to official documents by the priest of the cathedral V. Serafimov, which was later republished. Subsequently, the works of Pyotr Gnedich (“History of Arts from Ancient Times”, 1885) and Vladimir Stasov were published. Gnedich does not speak directly about St. Isaac's Cathedral, however, in his book, two of the five illustrations depict the appearance of the cathedral and its interior. Next to the image of Isaac there is a text where Gnedich talks about the "false classical style" - a superficial imitation of "bad late Roman models", transferring only external forms without a deep understanding of the essence of classical ancient art.

The first to criticize St. Isaac's Cathedral was Stasov, who called it "a dry and impossible building with a lot of shortcomings." His largely controversial judgments, however, gave direction to the study and evaluation of the building from an art history point of view.

An artistic analysis of the cathedral was presented in Igor Grabar's History of Russian Art (1910-1913). The art critic believed that the original design of the cathedral, known at that time from the surviving model, was much better than the final version of the building. Later elements of decor - complex luxurious architraves of spans and doors, heavy angels with torches, pilasters with rake - belonged to the so-called Nikolaev classicism, and in the era of Alexander I, such architecture "would have seemed too bourgeois". From an artistic point of view, the composition of the five-domed cathedral was also called unsuccessful, to correct which the architect, wanting to connect the small domes with the main body, came up with the technique of four ledges in the plan, on which he placed the domes. Best of all, according to Grabar, Montferrand succeeded in imposing porticos with grandiose granite columns.

After the 1917 revolution in literature, St. Isaac's Cathedral was presented as a "hotbed of obscurantism." The works of V. A. Belyaev, E. I. Vostokov, L. Finn, sustained in a similar spirit, are not scientific and are interesting only as evidence of time.

Art critic Alexei Nekrasov in his monograph "Russian Empire" (1935), although he attributed the cathedral to the late Empire, noted the general eclecticism of the building: the researcher compared the main dome with the dome of the Church of St. Nicholas in Potsdam, architect Karl Schinkel; Nekrasov considered the western pediment, reminiscent of classicism in proportions, to be so overloaded with sculptural decoration that even for the powerful columns supporting it, it seemed excessively heavy; in the details of the cathedral, the author found the splendor of Renaissance architecture, but noted their inconsistency with each other, and called the five-dome system far from the compactness and expressiveness of the temples of Vasily Stasov. According to Nekrasov, the significance of the cathedral for the architecture of Russia lay in the plane of picturesqueness of its individual parts, both in the exterior and in the interior.

In 1939, a monograph by Nikolai Nikitin, curator and restorer of the cathedral, Auguste Montferrand. Design and construction of St. Isaac's Cathedral and the Alexander Column. Valery Shuisky, a contemporary researcher of the work of Auguste Montferrand, believed that Nikitin's book was written "from the position of the vulgar sociology that prevailed in Soviet times and the uncompromising struggle against cosmopolitanism." The original author's text of the monograph, preserved in the form of a linotype, casts doubt on Shuisky's judgment. Nikitin's work formed the basis of the museum's excursion work in the cathedral in Soviet times. In 1940 and 1945, based on his research, the restorer defended his dissertations “Uneven settlement and deformation of the building of the Anti-Religious Museum (former St. Isaac’s Cathedral)” and “Auguste Montferrand. Design and construction of St. Isaac's Cathedral and the Alexander Column.

Art historians Natalya Evsina and Nikolai Khomutetsky in their major Soviet study “History of Russian Art” noted that the building of the cathedral, conceived during the heyday of Russian classicism, was built at a time when this style turned from progressive into reactionary, and because of this, the temple, although it belonged to one of the largest, most complex and interesting structures that completed the development of classicism in Russia, at the same time, its architecture showed the shortcomings characteristic of the works of the period of the second third of the 19th century. Using the example of St. Isaac's Cathedral, one can see how by the middle of the century the ideas about the monumentality of the architecture of buildings were distorted: the rigor and noble simplicity of the beginning of the century were replaced by a desire for pomposity, expressed in the congestion of facades with decor, the complication of the plasticity of walls, and the excessive enrichment of interior decoration. At the same time, the researchers noted the positive effect of the construction of a grandiose cathedral on the development of the Russian architectural school, which gave impetus to the development of building technology and the training of numerous builders and architects.

Architectural historians Tatyana Slavina and Vladimir Pilyavsky wrote that the main advantage of the cathedral was the “collegiate nature of the creative process”: “it is not so much the idea that triumphs here, but its implementation.” The scope of the construction was matched by an unprecedented amount of technical work, which became a testing ground for testing and implementing the latest technologies. The researchers wrote that, in general, St. Isaac's Cathedral, "excellently meeting the criterion of" magnificence ", adequately completed the search for architectural imagery corresponding to the spirit of the Russian Empire, which was carried out by several generations of Russian architects."

 

Condition and restoration of the building

Already in 1841, Montferrand himself noted that due to uneven sedimentation in the marble slabs with which the walls were sheathed, cracks appeared at the junctions of the bell towers with the wall. However, Montferrand reported to the Commission that the settlement of the building had already ceased. The changes that affected the columns turned out to be more serious - the settled bell towers "pulled the entire pediment behind them" (Nikitin), and the columns associated with the architrave deviated from the vertical. For those whose deviation was large enough, cracks appeared in its direction in the lower part of the rods, and on the opposite side of the base of the rods, the columns (beds) rose up. It was impossible to return the columns to their original position, and in order to ensure the operation of the entire bed, Montferrand decided to hammer copper wedges into the gaps between the beds and granite ingots. To hide the wedges and cracks in the shelf, a bronze fillet was put on the upper roller of the bronze base of the column.

A special committee was set up to monitor the course of the settlement, but no measurements of the resulting deformations were made. In 1846, the committee announced that the settlement had not affected the strength of the cathedral and that its process was completed. However, the marble cladding of the facades continued to burst, the columns deviated from the vertical (the maximum deviation was 160 mm), and marble modillions began to fall from the cornice. In 1873, when the architraves cracked due to a change in their original position, it was decided to overhaul the cathedral. The columns were given a vertical position, for which they arranged scaffolding that took the load of entablature with pediments, bronze capitals were removed and the upper parts of the columns were cut down. Cracked Ruskeala marble facing slabs on the façade were also replaced. Repair work was completed by 1898. In his report at the III Congress of Architects (1900), their leader E. Sabaneev described in detail the progress of work and noted in conclusion that, according to many years of observations, the building had stopped settling, which means that the columns should no longer change their position.

After a while, it became clear that the uneven settlement of the building continued. In 1927, N. P. Nikitin, who had been monitoring the state of the cathedral since 1918, conducted an instrumental survey of deformations. Nikitin determined the deviations of the columns of the porticos from the vertical, the direction and magnitude of the settlement of the foundations (it turned out to be the most uniform in the parts remaining from the construction of Rinaldi) of the main building, leveled the floor of the cathedral and the porticoes, the upper cast-iron balustrade and the bases of the round granite portico, as well as the laying rows in niches of pylons - where they are not covered with marble facing. The sedimentary movement of the building, according to the results of the survey, went in the direction from east to west and from north to south (central part) and from southeast to northwest (pylons, cast-iron balustrade, granite portico bases). The greatest deviation was found in the columns embedded in the bell towers. The foundations of the columns were repaired, for this it was necessary to saw and remove their bronze bases. The breakaway pieces of granite were removed, the cracks were washed and filled with cement mortar, the gaps between the base and the base of the columns were concreted, the bases were tightened with iron clamps.

In 1939, another instrumental survey was carried out, it turned out that the changes in the vertical deviations of the axes of the columns and corners of buildings compared to 1927 were negligible. In 1941-1942, as a result of leveling the vaults of the upper ceiling, the reasons for their deformation were determined, and the vaults were strengthened. The state of the load-bearing structures seemed to be a much more serious problem for the restorers - in 1950 their significant old damage was opened. It was necessary to find out how dangerous they are, and to develop methods for their elimination. In 1953, specialists from the Leningrad Polytechnic Institute took up the study of the main load-bearing structures. The specialists of the institute came to the conclusion that the foundation of the cathedral is in a stable state, the condition of the laying of the foundations was determined as “quite good”, the wooden piles could not be subject to rotting, since the level of their heads was below the groundwater level. The strength of the piles was checked by calculating the stresses in their sections and found to be sufficient.

Another serious task was to determine the strength of the pylons and the nature of the deformations (cracks) that were found in their niches. In 1910, Academician M. Preobrazhensky performed a static calculation, according to which the stress in the vertical part of the pylons was three times more than the allowable one. Professor P. I. Dmitriev, having made his calculation in the same 1910, came to the conclusion that the stress of the pylons exceeds the allowable for brickwork. In 1953, the commission of the Polytechnic Institute examined the pylons, made new static calculations and confirmed the conclusion that the central pylons were overstressed. Several projects have been proposed to increase the strength of load-bearing structures. However, due to later doubts that the latter were in disrepair, none of the projects was implemented. From 1965 to 1966, pylons (including wall pylons) were examined by non-destructive methods. The cracks discovered earlier were not through (their depth varied from 20 to 100 cm), and the strength of the brickwork in the places of the chambers and niches was recognized as sufficient to ensure the further reliable operation of the building. The reasons for the appearance of cracks in the pylons were recognized as "the physical and mechanical properties of brickwork and granite laying rows", as well as the impact of the microclimate of the cathedral's premises.

According to the professor of St. Petersburg Polytechnic University Valery Golod, “from a mechanical point of view, the state of the cathedral is in an emergency. The margin of safety is sometimes from two to six times. But what part of this reserve has been exhausted, and what part continues to hold the structure? You can't turn a blind eye to this."
