The little castle of San Pietro sits on a hill at 354 metres not far from Loretello. It was mentioned for the first time when some of its inhabitants filed a castellania act at Rocca Contrada.
...Although its XV urban layout remains intact, very few traces of the original structure have been preserved. The defensive stone wall on the brickwork slope and the walkway, however, have survived to our day. Just outside its walls is the Madonna di Montevago sanctuary (XVI century) which boasts a lovely fresco of the Virgin Mary done by Venanzio da Camerino and Piergentile da Matelica.
