Castellammare del Golfo is an Italian municipality of 15,201 inhabitants in the province of Trapani in Sicily.

It bases its economy on tourism and, less than in the past, on viticulture and fishing. Every two years the historical re-enactment of the attack on the port by the English is celebrated, foiled, according to legend, by the arrival of the Madonna di l'Assicursu (Madonna of Rescue).

The town stands on the slopes of the Monte Inici mountain complex and gives its name to the gulf of the same name overlooking the castle, bordered to the east by Capo Rama and to the west by Capo San Vito.

The Castellammare coast is beautiful and varied: it ranges from the large fine sandy beach of Playa, to the east of the town, to the rocky stretch interspersed with suggestive coves to the north-west of the town centre.
