What to See on San Pietro di Castello? Island, Basilica, Feast and more. Here's everything you need to know below.
1. Basilica of San Pietro di Castello
The island's main attraction is undoubtedly the Basilica of San Pietro di Castello, venice's official cathedral until 1807. The first church on the site was constructed in the ninth century and later rebuilt after fire damage. The church served as an independent episcopal seat from 775 to 1451 and as the seat of the Patriarch of Venice until 1807, when the title was transferred to san marco. The present building reflects major renovations through which it was rebuilt in the late sixteenth and early seventeenth centuries. Its facade follows a design by Andrea Palladio dating back to 1556 and was later completed by Francesco Smeraldi, with the current façade built between 1594 and 1596 as part of the project. It has a Latin-cross plan with three naves and a central nave beneath a dome.
Inside, the high altar, designed in 1649 by Baldassare Longhena, contains the urn of Saint Lorenzo Giustiniani, the first patriarch. Other highlights include the legendary marble throne of St Peter, an unusual cross of wood and embossed copper, works by Paolo Veronese and Marco Basaiti, and Pietro Liberi's masterpiece The Plague of Serpents. The vendramin chapel contains Luca Giordano's Madonna and Child.
2. The Bell Tower
Standing beside the basilica is the distinctive bell tower, one of the most recognizable landmarks in the area. Dating from 1482 to 1492, the campanile dominates the surrounding landscape and serves as a visual reference point for boats approaching from the eastern lagoon. Designed by Mauro Codussi, it is made of stone and is the only campanile in Venice clad entirely in white Istrian stone.
