The basilica of San Pietro di Castello is an important place of 
		worship in Venice, until 1807 the cathedral of the patriarchate of 
		Venice; it is located at the north-eastern end of the city of Venice, in 
		the Castello district, not far from the docks of the Arsenale.
		The church has the dignity of a minor basilica and is part of the Chorus 
		Venezia association.
As reported by the chronicler Giovanni Diacono, the church of San 
		Pietro was begun around the time of the expulsion of the patriarch of 
		Grado Fortunato, while the consecration took place nine years later, in 
		the period in which the doge Obelerio was killed; therefore, it should 
		have been built starting from 822-823 and completed around 831-832. The 
		testimony is partially confirmed by the will of Orso, bishop of Olivolo 
		since 822, which states that it was he who laid the foundations of the 
		building.
This means that the diocese of Olivolo, founded in 
		775-776, originally had another cathedral. Those traditions that would 
		like St. Peter's founded in the 7th century and initially consecrated to 
		Saints Sergius and Bacchus, whose relics lie here, could have some truth 
		to them. This would suggest the existence of an older church in place of 
		which the current one was built in the first half of the 9th century. 
		Other scholars have theorized that the first cathedral of Olivolo was 
		the church of San Teodoro, the current basilica of San Marco.
		Nothing remains of the primitive building, except for a fragment of 
		mosaic, preserved in the Lando chapel.
In 1120 a fire devastated 
		the church; the new structure, faithfully reproduced on the plan of 
		Jacopo de' Barbari of the sixteenth century, assumed a more majestic 
		dimension, with an adjacent baptistery, dedicated to San Giovanni 
		Battista, now lost.
In 1451, with the suppression of the 
		Patriarchate of Grado and the establishment of the Diocese of Castello 
		as the Patriarchate of Venice (bull of Pope Nicholas V), the basilica of 
		San Pietro became the new patriarchal cathedral.
It was the 
		patriarch Antonio Contarini who decided to carry out restoration work on 
		the ceiling, vaults and floor between 1508 and 1524. Between 1512 and 
		1526 the minor chapels were rebuilt and the furnishings and decorations 
		were redone.
In 1556, having become patriarch of Venice, Antonio 
		Diedo stipulated a contract with Andrea Palladio on 7 January 1558, who 
		however withdrew in 1559, on the death of Diedo; this would have been 
		his first intervention in Venice. Palladio probably arrived at the 
		prestigious assignment, which was not completed, thanks to Daniele and 
		Marcantonio Barbaro, who are guarantors of the contract with the masons 
		in January 1558.
The works resumed in 1596 under the direction of 
		Francesco Smeraldi, commissioned by the patriarch Lorenzo Priuli, to 
		whom we owe the construction of the façade. From 1619 Gerolamo Grapiglia 
		took care of the creation of the interiors, under the patriarchate of 
		Giovanni Tiepolo.
From 1630 to the fall of the Republic, the 
		Serenissima Signoria made an annual pilgrimage to the basilica, on 
		January 8, to celebrate the city's liberation from the plague.
		With the fall of the Republic of Venice and the loss of the function of 
		the basilica of San Marco as a state church, subject to the authority of 
		a ducal primicerio, in 1807, at the behest of Napoleon, the patriarchal 
		seat was transferred to San Marco. At the same time, the canonical 
		chapter of San Pietro di Castello was joined to the palatine chapter of 
		San Marco.
The canonical status of the cathedral basilica 
		(rectius patriarchale) and of the basilica of San Pietro di Castello is 
		regulated by the bull of Pius VII Ecclesias Quae, dated 24 September 
		1821. Once the cathedralship was definitively transferred to San Marco, 
		San Pietro was granted the dignity of minor basilica "ad instar 
		basilicarum minorum almae Urbis" and its parish priest obtained the 
		title of archpriest; moreover, the archpriest is, during munere, a canon 
		of the cathedral basilica of San Marco.
With the transfer of the 
		headquarters, the monastery adjacent to the basilica of San Pietro was 
		transformed into a powder magazine by order of Eugene de Beauharnais, 
		viceroy of Italy.
During the First World War the dome was hit 
		twice by incendiary bombs which caused the destruction of the lantern.
The current plan can be traced back to 1120 when a fire devastated 
		the previous church in 841. The structure had three naves, a tripartite 
		façade and circular apses. Next to it stood the baptistery of San 
		Giovanni Battista, now lost.
The current façade does not exactly 
		reflect Andrea Palladio's initial project of 1568, but is faithful to 
		its essential lines. We note a tripartite system, with the central part 
		raised, resting on four semi-columns, there are bases that end in a 
		tympanum. The fundamental theme foresees a major order corresponding to 
		the central nave, and a minor one in relation to the lateral ones. The 
		whole is decorated with a nineteenth-century bas-relief depicting La 
		Carità, by the sculptor Marsili. The style can be called classic.
		
The building has a Latin cross layout with three naves divided by 
		three arches each, with an altar inside; at the crossroads with the 
		transept is the dome.
The deep presbytery, which follows the 
		large central nave of the church, is flanked by two side chapels.
		
The great high altar in which the remains of San Lorenzo 
		Giustiniani, the first Patriarch of Venice, are kept, dates back to 
		1646. It was the work of Clemente Molli, who was also given the task of 
		sculpting some of the statues present in it, based on a design by 
		Baldassarre Longhena, who also designed the chapel dedicated to Cardinal 
		Francesco Vendramin, on the left aisle.
The Chair of St. Peter, which according to tradition belonged to the 
		Apostle himself when he was bishop of Antioch, is said to have been 
		donated to Doge Pietro Tradonico by the Eastern Emperor Michael III, in 
		reality it is built from a back obtained from a ancient Islamic funerary 
		stele, bearing Arabic decorative motifs and Kufic engravings of verses 
		from the Koran: Sura III, vv. 192-194 "O Lord! Give us what you promised 
		us, through the mouth of Your Angels, and do not shame us on the day of 
		the resurrection" and Sura XXIII, v. 118 "And You forgive! Be merciful! 
		You are among the best of the compassionate!"
In the right aisle, 
		San Pietro in Cattedra and four Saints by Marco Basaiti, 16th century.
		
In the left aisle the Vendramin chapel, dedicated to Our Lady of 
		Mount Carmel contains bas-reliefs by Michele Ungaro, 1675 and houses 
		Luca Giordano's 1650 altarpiece of the Madonna and Child with Souls in 
		Purgatory. Also in the left aisle is the Lando chapel, with a mosaic 
		altarpiece by Arminio Zuccato, probably based on a cartoon by Jacopo 
		Tintoretto, 1570.
Between the two chapels are works by Veronese 
		from around 1585, Saints John the Evangelist, Peter and Paul, the 
		Immaculate Conception by Giovanni Maria Morlaiter, 18th century, and The 
		Martyrdom of Saint John the Evangelist, by Padovanino.
Among the 
		major paintings in the basilica, we can identify the Supper at Emmaus by 
		Pietro Malombra and Antonio Vassilacchi, on the left wall of the portal.
		
While on the right, by Jacopo Beltrame, 16th century, Dinner in 
		Simone's House, two statues by Orazio Marinali, Faith and Meditation 
		surrounding the Crucifix by Jacopo Strada, 18th century.
St. 
		George and the Princess and the Dragon, by Marco Basaiti; since 1985 it 
		has been on deposit at the Gallerie dell'Accademia.
In the chapel 
		to the right of the main altar you can admire the large fresco by Pietro 
		Ricchi (known as il Lucchese) The adoration of the Magi (1658).
On the choir loft, behind the high altar, there is the Nachini opus 
		276 pipe organ, built in 1754 and restored by Pietro Bazzani in 1898.
		
The instrument, with fully mechanical transmission, has a single 
		keyboard of 57 notes with a first eighth note and an 18-note pedal board 
		(the 18th note corresponds to the drum), constantly joined to the manual 
		and with a first octave note.
The baroque wooden case is painted 
		in imitation marble and has relief decorations in gilded wood. In the 
		centre, the exhibition, made up of 25 main pipes with horizontally 
		aligned shield mouths, arranged in a single cusp with lateral wings.
The bell tower started in 1463, was damaged by lightning, and rebuilt 
		in 1482 by Mauro Codussi, in exposed Istrian stone. The dome on the top, 
		in wood covered with lead plates and decorated with a small lantern, was 
		demolished and rebuilt in 1670, on 17 October 1822, struck by lightning, 
		it was definitively destroyed.
Given the slope of the bell tower, 
		the bells ring with falling clappers. It houses 5, of which the 2 large 
		ones were merged by the De Poli Brothers of Ceneda (TV) in 1870 and the 
		3 small ones by Domenico Dalla Venezia in 1825: I: D3 flat II: Eb3 flat 
		III: F3 IV: G3 flat V: Ab3
