Cave di Cusa

Cave di Cusa, also known as Rocche di Cusa, is an ancient stone quarry in Sicily, three kilometres south of Campobello di Mazara in the province of Trapani. It stretches 1.8 kilometres along an east-west ridge. Quarrying began in the first half of the 6th century BC, and the stone was used to build the temples of the Greek city Selinunte. Work ceased abruptly in 409 BC, when the Carthaginians captured the city. The site was simply abandoned, leaving columns and blocks half-hewn from the rock, still in place where they were cut. It is now an official Sicilian Archaeological Zone and a popular place to visit.
