Rocca Paolina

The Rocca Paolina (Pope Paul’s Fortress) is a fortress designed by Antonio da Sangallo the Younger. The fortress was built in 1540 during the pontificate of the Pope Paul III, as a sign of the renewed papal dominion after the so-called “War of the Salt”. To build this fortress, an entire district was razed to the ground, including all the houses of the Baglioni family that previously was keeping control of the town. The fortress was partially destroyed in 1848 and completely demolished in 1860 with the unification of Italy. Today, only the underground structures remain, and part of the old streets of the medieval Perugia inside the Rocca Paolina are accessible.
