Trapani is a city in western Sicily with a crescent-shaped coast. In the western tip, overlooking the Egadi Islands, there’s the Torre di Ligny watchtower, dating back to the 17th century,which houses the Museum of Prehistory and Marine Archeology. Heading north from the port, the Church of the Purgatory preserves wooden sculptures that parade through the city during the Procession of the Mysteries at Easter.
