Calasetta is opposite S.Pietro's Island, in the south-western part of Sardinia.  Its population, composed mostly of fishermen and farmers, comes from the Liguria region.  During the XVIII Century, some Ligurian people living in Tunisia on the island of Tabarka, asked the King of Sardinia Carlo Emauele I for the permission to move to the island ofS.Antioco.  Thus, in 1770, about 132 of these people arrived in Sardinia.
Calasetta is an important tourist destination, thanks to its indented coastline mixed with wonderful, white sand beaches.  Among these beaches and worth mentioning, is the Sottotorre beach, near the eighteenth-century tower not very far from Calasetta's harbour.
On the outskirts of town, you'll find the Salina beach and the Grande beach, both surrounded by junipers.  Behind them is a tourist village and, to the west near Punta Maggiore, you can see Calasetta's once famous tuna fishery, no longer in use today and the Mangiabarche lighthouse.
Continuing along, the coastline appears rocky and has steep slopes.  To be noted is the Cala Lunga beach, with its turquoise-coloured water; a bay sheltered from the wind.
The territory also offers very attractive archaeological sites including Nuraghe, domus de janas, megalithic constructions and also old kilns for limestone decalcification.
In Sisineddu, there are the Nuraghe Rassetto and numerous natural caves.  In the Bricco area you'll find the remains of the Nuraghe Scarperino and in the Nido dei Passeri area, the Nuraghe Acqua Dolce.
