San Pietro di Castello (church)

The earliest structure on the site dates from the 7th century.[1] It was one of the eight churches founded by St. Magnus (Italian: San Magno), the Bishop of Oderzo, who came to the Venetian lagoon during this period. At the time there was no city but simply a collection of small communities scattered throughout the marshy islands. In a vision St. Peter (Italian: San Pietro) appeared to Magnus and instructed him to found a church where he saw oxen and sheep grazing side by side. The location was found and St. Magnus built the church, dedicating it to St. Peter.[2][3]

The first Bishop of Castello was invested in 1091.[4] In 1120 a fire destroyed the church requiring a new structure to be built. This was grander than the previous building (as seen on a map drawn by Jacopo de' Barbari in 1500) and had an adjoining baptistery dedicated to St. John the Baptist (since destroyed). In 1451, and despite being some distance from the political and economic centre of the city, San Pietro became the seat of the Patriarch of Venice.[1] Following this the building began to see significant investment. During the 1480s Mauro Codussi rebuilt the church's campanile using white Istrian stone, the first example of this seen in Venice.[1] Between 1508 and 1524 the Patriarch Antonio Contarini restored the floors and ceiling. At the same time minor chapels were re-built and the church was decorated with new furnishings.

In 1558 Andrea Palladio, in his first commission in the city of Venice, prepared an improved design for the facade and interior of San Pietro.[5] However, the Patriarch who had commissioned Palladio, Vincenzo Diedo, died before the plans could be implemented. Later, between 1594 and 1596 the architect Francesco Smeraldi implemented a modified and less ambitious version of Palladio's original design, the changes possibly attributable to a lack of funds.[4][6][7]

In 1807 St Mark's Basilica became Venice's official cathedral church instead of San Pietro. After 1807 the church saw increased neglect and suffered from firebomb damage during First World War. It wasn't until conservation organisations intervened during the 1970s that the church was restored to its former condition. The church itself is a member of the Chorus Association of Venetian Churches.

The church exhibits a muted facade compared to other Palladian designs in Venice. It features a prominent set of four engaged columns with Composite capitals supporting the main pediment and entablature. This is then flanked by a double broken pediment.[8]

The church has a large dome which indicates the church's ecclesiastical importance, sharing an affinity with San Giorgio Maggiore and Il Redentore both churches designed by Palladio. The dome is supported on a drum which has rectangular windows cut into it to let light into the building.

The church's campanile is one of the most precarious in Venice.[1]

Interior

The building has a large central nave with Latin aisles. The transept crosses the church, separating the nave from the presbytery. The crossing point is capped by a large dome. The Vendramin Chapel, located off the left aisle, was designed by the baroque architect Baldassarre Longhena, as was the high altar which he constructed during the middle of the 17th century.[1][9] The organ was constructed by the Dalmatian craftsman Pietro Nachini who was working in Venice during the 18th century.
