The church was originally built in the early Christian period and has been destroyed and rebuilt multiple times due to fires.
The interior five-aisle design was directly modeled by Giulio Romano after the original, now-demolished Constantinian Basilica of Saint Peter in Rome.
The bell tower contains seven bells tuned to the scale of B-flat major, cast in the early 20th century.
The crypt, though not always accessible to the public, contains the remains of early local bishops and saints.
The Cattedrale di San Pietro, also known as the Mantua Cathedral, stands on Piazza Sordello and serves as the seat of the Bishop of Mantua. The current structure is a synthesis of architectural eras, featuring an 18th-century facade by Nicolò Baschiera that masks a complex interior history. The building houses a Gothic side flank and bell tower, preserved from a 14th-century iteration following a fire. Giulio Romano, a pupil of Raphael, redesigned the interior layout during the 16th century, incorporating a five-aisled plan inspired by Old Saint Peter's Basilica in Rome. The interior includes significant artwork, including works by artists of the Mantuan school. It serves as the primary religious site of the city and remains an active parish church.
From the center of Piazza Sordello to capture the full scale of the facade against the sky.
Walk around the left exterior of the building to see the distinct transition between the Romanesque/Gothic brickwork and the neoclassical facade.
Check the side chapels carefully, as they contain paintings by 16th and 17th-century masters that are often overlooked by visitors focusing on the main altar.
Visit during the late morning to catch natural light filtering through the clerestory windows.
Do not attempt to enter or take photos during active liturgical services.
