The Pieve di San Pietro dates back to 1100 and was erected on the ruins of an ancient Roman temple that has now disappeared. Its admirable façade is divided into large quadrangles. The portal has a hanging porch, surmounted by a small mullioned window. The interior has three naves divided by pillars with an elevated presbytery and a crypt. The church was included by the French actor Alain Delon in his film "The First Night of Quiet".
