The Church of St. Andrea was built in the 12th century over a pre-existent early Christian basilica and over an Etruscan temple as bear witness the remains founded in the Crypt. The facade is adorned by the elegant portal with lunetta featuring the Madonna with Child and Saints. On the right side emerges the battlemented dodecagonal bell tower with three orders of two-light windows The church interior has three naves with pillars and cross vaults. On the walls are several remains of frescos among which one is attributed to Benozzo Gozzoli. As mentioned above under the floor opens the Crypt in whose interiors  is possible to see the rest of the original mosaic floor. Every year, on August 14, late in the evening , takes place a religious procession with the carriage of the statue of Virgin Mary. The event dates back to 1338
