Its narrow, winding streets, small piazzas and noble palazzi are guarded by precipitous drops and formidable defence walls within two main gates: Porta San Pietro on the east, built into a wall high above the Via Cassia, and Porta del Ponte (dell’Orologio) on the west, where it blends with the ancient Anguillara castle. Federico Fellini shot a small scene for his famous film La dolce vita just outside Castrovecchio beneath the Porta del Ponte. To the west of this gate stretches the Renaissance (1380–1600) section of Capranica; it is closed off from the newest section of the town, which lies outside the town walls, with the 17th century gate, Porta Sant’Antonio.
