City Gates and Walls Museum The Museo delle Porte e delle Mura Urbiche of Perugia is held inside the most imposing medieval gate of Perugia, a grandiose crenellated construction—a gatehouse-tower built with bricks, quoin and ashlars—called Cassero di Porta Sant’Angelo, standing at the upper end of Corso Garibaldi, in the homonymous quarter, Rione di Porta Sant’Angelo. The Museum display is arranged following the history—reconstructed through the documentation collected over the centuries—of the three town-wall belts of Perugia. At the entrance, there are some informative panels describing the history of the town, over the centuries, and some scale models reproducing the three phases of construction and expansion of the walls: the ancient one is the Etruscan defensive wall, then the medieval one—precisely the Cassero gatehouse-tower—and then the Renaissance one. On the upper floor there are the reproductions of the main gates, one for each phase of expansion of the belt: scale models of the Arco Etrusco, the Cassero di Porta Sant’Angelo and Porta San Pietro, the low-relief decorated Renaissance gate sculpted by Agostino di Duccio. Up on the roof of the tower the visitor, surrounded by the Guelph battlement, can enjoy a spectacular panorama over the town.
