Trapani is a city in western Sicily with a crescent-shaped coastline. At the western tip, offering views as far as the Aegadian Islands, is the 17th-century Torre di Ligny watchtower. It houses the Museo di Preistoria e del Mare, with archeological artifacts. North of the harbor, the Chiesa del Purgatorio church holds wooden sculptures that are paraded around the city during Easter’s Processione dei Misteri.
