The island of Sant'Antioco is situated in the south-western part of Sardinia, connected to the motherland by an artificial isthmus and is the largest among the smaller Sardinian islands. Its territory includes the two urban centres Sant'Antioco and Calasetta along with various, smaller towns, for the most part seaside resorts. Situated at the foot of Castle Hill, Sant'Antioco is the island's main town. It looks like a typical fisherman's village, with its low houses and their red roofs. Its streets are narrow but it has a complex urban structure. Sant'Antioco's history dates back thousands of years.
