Already present in the 14C and rebuilt from 1339 on by bishop Gotifredo of Mantua, this church features three large windows on the facade. Inside, it has three aisles and a transept. The central aisle and transept are rounded, and the central dome is covered with frescoes; the two side aisles have a coffered ceiling.

The present design is the product of restoration by the architect Giovan Battista Vergani, in 1829 and 1831. The new hammered-concrete facade with large arches dates from 1921. The bell-tower was elevated from 39 to 49 metres in 1950. Originally, the top of the facade was set back from the other buildings and the entrance portico was a continuation of the porticoes in the square, with round arches.
