Columns of San Marco and San Todaro (Piazza San Marco columns), Venice

The columns of San Marco and San Tòdaro, or columns of Piazza San Marco, in Venice, are two tall carriages in marble and granite, placed at the entrance to the St Mark's area towards the pier and the San Marco basin. They are surmounted by the statues of the patron saints of the city: Mark the Evangelist in the traditional form of a lion and San Tòdaro (Venetian name of the Byzantine Theodore of Amasea), while on the bases they have high reliefs depicting the trades that were carried out in the square.

 

Characteristics

The two columns, together with the docks of Palazzo Ducale and the Marciana Library, constitute the monumental access to the square for those coming from the sea.

According to tradition, the columns were erected by Nicolò Barattiero under the Doge of Sebastiano Ziani (1172-1178), when the square was enlarged and monumentalised. The enormous columns, transported from the East as spoils of war, were originally to be three, but the third carriage was lost together with the ship that carried it during the landing. The shipwrecked column had to sink deeply into the mud of the seabed, so much so that "looking for it twenty years after the sinking by a specially appointed master, by feeling the bottom with a long pole, it could not be found in any way".

However, more recent interpretations date the erection of the columns to the second half of the 13th century. The marbles of the two columns (Egyptian red marble for the column of S.Todaro and Troadense marble for the column of S.Marco) were widely used for the erection of columns in late antiquity, a fact which makes their origin from Constantinople almost certain . Therefore it is extremely probable that the arrival of the columns in Venice, as for most of the Byzantine remains present in the lagoon, can be traced back to the period of the Latin Empire of Constantinople, between 1204 and 1261.

The bases are made of Istrian stone, a material that began to be used in Venetian construction starting from the last quarter of the 13th century, after the closure of the Greek marble markets following the reconquest of Constantinople by the Byzantines. In the bases there are high reliefs depicting trades, evidence of the period prior to the monumentalization of Piazza San Marco in the 16th century: before the 16th century, the square was the site of intense economic activity. The reliefs were made in a "realistic" style, which arrived in Venice in the second quarter of the thirteenth century and of which various works can be observed in the decorations of the Basilica: among these in particular the reliefs of the bases are indebted to the representations of the crafts of the arch greater, even if their lower quality suggests that they are not the work of the same master.

Even the style of the capitals of the columns seems to confirm the dating of the erection of the columns to the 13th century. They are made of Veronese stone with pink streaks and are in the Venetian-Byzantine style, as confirmed by their resemblance to Ruskin's second and third styles. The capitals of the columns are also very similar to the decorations of the tomb of Denaro Odifredi in Bologna, built around 1265 by Venetian workers.

The column that stands on the side of Palazzo Ducale holds the winged lion, symbol of San Marco, patron saint and symbol of the city and the Venetian state since 862. It is a very ancient Greek or Syrian bronze sculpture, probably originally a chimera, to which wings were later added. On the side of the Library is, however, that of San Teodoro, Byzantine saint and warrior, first protector of the city, depicted in marble in the act of slaying a dragon. The bust comes from a classical statue of a Roman emperor, while the head, the halo, the arms and the legs resting on the slain dragon are from the Middle Ages. The sculpture is a copy of the original exhibited at the entrance to Palazzo Ducale. According to a legend reported by Sansovino in the 16th century, the lion of S. Marco looks east to symbolize the role of Venice as protector of Christianity in the East, while the statue of S. Teodoro facing west would symbolize the defensive attitude of the Serenissima towards the Land. This explanation of the different orientation of the two statues is evidently prior to the 16th century (at the time the Serenissima had already established the Dominion in the Mainland) and therefore would date back to the era prior to the 14th century, probably to the period prior to the fall of Acre in 1291 .

Under the columns, in the Middle Ages and the Renaissance, wooden shops were placed, however already from the mid-eighteenth century the space between the two stelae was destined for the place of capital executions, so much so that the superstitious use still persists among the local population not to cross the clearing between the columns. A Venetian way of saying also derives from this use: "Te fasso veder mi, che ora che xe" (I'll show you what time it is), derived from the fact that those sentenced to death, with their backs to the basin of San Marco last thing they saw was the clock tower. The space between the two columns was also the only "free zone", in which it was legal to gamble, a privilege granted to Nicolò Barattiero (or Barattieri), or the one who managed to find a way to erect the heavy structures left stretched out on the ground for a long time: through the use of large ropes that were fixed to the end of a column and then wet, which, as they dried, exerted such a traction as to allow them to be raised a few centimeters and to insert wooden wedges underneath, the builder from Bergamo, who had already distinguished himself in the construction of the belfry of the bell tower of San Marco, thus accomplished the task of lifting the heavy columns without damaging them. As a reward, he was granted the exclusive right to gamble at the foot of the two columns, which allowed him to become quite rich.

 

History

Origins and Arrival in Venice
The columns originated in the eastern Mediterranean, likely as spoils of war acquired during Venice's expansive maritime campaigns in the 12th century. Historical accounts vary on their exact provenance and arrival date, reflecting the blend of legend and fact common in Venetian historiography. One prevalent narrative attributes their transport to Doge Domenico Michiel in 1125 or 1127, following his military expedition to Caesarea (in modern-day Israel) or Tyre (in modern-day Lebanon) during the Venetian Crusade against the Fatimid Caliphate. According to this version, the columns were part of the booty from these conquests, symbolizing Venice's growing dominance in the Levant.
Alternative sources suggest a Byzantine origin, possibly from Constantinople (modern-day Istanbul), aligning with Venice's deep ties to the Eastern Roman Empire. Archaeological analysis of the materials—red Egyptian granite for the Column of San Todaro and troadense granite (from the Troad region in Turkey) for the Column of San Marco—points to Late Antique Roman construction in the eastern empire, supporting a Constantinopolitan source. This theory posits that the columns were looted during the Fourth Crusade (1202–1204), when Venice sacked Constantinople, and erected later in the 13th century, around 1268. However, most historians favor the earlier 12th-century timeline, as Venetian chronicler Francesco Sansovino documented their arrival from Constantinople around 1150.
A persistent legend claims there were originally three columns, transported on separate ships. During unloading near the Molo (the quay in front of the Doge's Palace), one vessel capsized, and the third column sank into the muddy lagoon bed. Despite attempts, it was deemed too heavy to recover and remains lost underwater to this day, fueling modern quests by divers and historians to locate it. The surviving pair lay abandoned on the shore for decades—possibly 50 to 100 years—due to their immense weight (each estimated at over 100 tons) and the engineering challenges of erecting them.

Erection and the Role of Nicolò Barattieri
The columns' erection marks a triumph of medieval engineering and Venetian ingenuity. In 1172, during the reign of Doge Sebastiano Ziani (1172–1178), Lombard engineer Nicolò Barattieri (also referred to as Nicolò Lombardo or Nicolò dei Barattieri) proposed a solution. He devised a method using wet ropes: thick cords were wrapped around the columns and soaked in water, causing them to expand and gradually lift the pillars upright as they dried and contracted under tension. This feat, completed between 1172 and 1177, transformed the Piazzetta into a grander space, part of Ziani's broader urban renewal that included expanding the square and reclaiming land from the lagoon.
As a reward, the Venetian Republic granted Barattieri exclusive rights to operate gambling tables between the columns—a privilege in a city where gambling was otherwise strictly regulated. This "free zone" for games of chance persisted until the 18th century, when the site shifted to a darker purpose.

The Statues Atop the Columns
The columns' crowning statues add layers of symbolism and antiquity. The Lion of San Marco, a bronze sculpture dating to the Hellenistic period (possibly 4th–3rd century BCE), is believed to originate from the eastern Mediterranean, perhaps Persia, Anatolia, or even China (as a chimera-like figure). It was modified in Venice with added wings to represent St. Mark's evangelistic symbol from the Book of Revelation. Acquired as war booty, likely from Constantinople, it embodies Venice's transition from Byzantine vassal to independent power.
The statue of San Todaro, a Byzantine work from the 9th–10th century, depicts St. Theodore Tiron (a warrior saint from Amasea in Turkey) slaying a dragon, symbolizing triumph over evil. Theodore was Venice's first patron before St. Mark's relics arrived in 828 CE, smuggled from Alexandria in a barrel of pork to evade Muslim guards. The statue, composed of marble fragments (head from a Roman emperor, body from a Byzantine saint), stands on a crocodile-like creature, blending pagan and Christian motifs.

Historical Uses, Events, and Transformations
From their installation, the columns marked the ceremonial entrance to Venice's civic center, where doges were proclaimed and foreign dignitaries arrived. By the 18th century, the space between them became the site of public executions, with condemned prisoners facing the square's clock tower for their final view. Traitors, murderers, and political offenders were hanged or beheaded here, including notable figures like the conspirators in the 1355 plot against Doge Marino Falier. This grim history led to the columns being dubbed the "Columns of Doom."
The columns survived Venice's fall to Napoleon in 1797 and subsequent Austrian rule, with restorations in the 19th and 20th centuries addressing weathering and structural issues. During World War II, they were protected from bombings, underscoring their cultural importance.

Legends, Superstitions, and Cultural Legacy
Superstition surrounds the columns: Venetians traditionally avoid walking between them, believing it brings bad luck due to the executions. The lost third column inspires tales of hidden treasure or curses, with modern expeditions using sonar to search the lagoon bed.
Today, the columns remain integral to Piazza San Marco, a UNESCO World Heritage site, symbolizing Venice's layered history of conquest, faith, and resilience. They continue to draw millions, standing as silent witnesses to over 800 years of the city's evolution from a maritime republic to a global cultural icon.
