Originally this church was the chapel of the castle. Incorporated into the walls, the church has changed considerably during the Fascist period and today is no longer possible to recognise its initial structure. The original part is represented by the impressive exterior walls that include a cylindrical tower. Inside are the reminder of the fresco of the 'Circumcision of Jesus', the Tabernacle of the fifteenth century and paintings by Pinturicchio and Maratta. The baptismal font is made from a fragment of a column with two opposing Corinthian capitals.
