According to tradition, it was in this place that Saint Marinus decided to build the first chapel in honor of St. Peter. The current building is the result of many restorations designed to reinforce the structure. The interior is in Neoclassical style and is characterized by a domed ceiling with golden decoration. The polychrome marble altar, on which you can admire the statue of St. Peter by Enrico Saroldi, and the frontal come from the ancient Pieve. In the apse, carved into the rock, you can see two stone beds, which are still attributed miraculous properties as, according to tradition, they belonged to the Saints Marinus and Leo.
