 They held the town and its castle until the 17th century, apart from two short periods in 1436–47 and in the early 16th century, when it went to Cesare Borgia.According to some sources, the town was destroyed by Renzo da Ceri's troops during the conflict between Pope Clement VII and the Colonna, and by the imperial troops in the wake of the Sack of Rome (1527).After a period as a direct Papal rule, it was sold in part to the Rospigliosi family, who held it until 1870, when it became a commune as part of the newly formed Kingdom of Italy.
