Rocca of Montestaffoli, San Gimignano

An imposing fortress from the 14th century belonged to Lombard Astolfo and later turned into Dominican Convent. Originally, Rocca of Montestaffoli was built by the Florentines, to protect the town from invaders and locals' uprising. Only one of the fortress' turrets is open to the public, however, it offers an enchanting view of the town's historical center.
