The Norman Castello di Venere was built in the 12th and 13th centuries over the Temple of Venus, long a site of worship for the ancient Elymians, Phoenicians, Greeks and Romans. The views from up top, extending to San Vito Lo Capo on one side and the Saline di Trapani on the other, are spectacular. To arrange midweek visits in winter, phone at least 24 hours in advance.
