From the 12th century to the 13th century. This structure presents one nave and its chancel with an oustanding apse in arcade. There is a tower over the crossing. The atrium is in the south façade. Inside, there is a Gothic chapel belonging to the Del Campo family with a revered image of Saint Nicholas from Bari that was originally in a church under that advocation, and important paintings by Ambrosio Benson and Jacopo da Pontormo. In the underground, by the apse, there are remains of a previous temple.
