A once-massive 16th-century fortress (Palazzo della Provincia) is now known as the Rocca Paolina. Pope Paolo III Farnese built the monstrosity in the 1540s, wiping out entire sections of what had been a wealthy neighbourhood. Now used as the throughway for the scale mobili, you can still see former homes of Perugia’s powerful medi­eval families, capped with the bricked-over roof of the papal fortress. Its nooks and crannies are now used for art exhibits throughout the year, and the last weekend of the month sees the antiques market held here.
