La Rocca

It is the highest part of the town( 411 m. on the sea level). The Pope Gregorio IX built it to strengthen his power over the citizens in 1373. The monastery of San Leucio and some private houses were demolished to obtain enough room. Then in 1503 Ludovico degli Atti demolished it and now only the Mastio, the big circular tower, and the remains of fortification works dominate the valley.
