Sulcis in the context of Province of South Sardinia

San Pietro Island (Italian: Isola di San Pietro, Ligurian Tabarchino: Uiza de San Pé, Sardinian: Isula 'e Sàntu Pèdru) is an island approximately seven kilometres (four nautical miles) off the South western Coast of Sardinia, Italy, facing the Sulcis peninsula. With an area of 51 square kilometres (19+3⁄4 sq mi) it is the sixth-largest island of Italy by area. The approximately 6,000 inhabitants are mostly concentrated in the fishing town of Carloforte, the only comune in the island. It is included in the province of South Sardinia. It is named after Saint Peter.

The island is connected by regular ferry service to Portovesme and Calasetta.

Sant'Antioco (Italian pronunciation: [santanˈtiːoko]; Sardinian: Santu Antiogu) is a town and municipality on the island of the same name in southwestern Sardinia, in the Province of Sulcis Iglesiente, in the Sulcis subregion. With a population of 10,451, the municipality of Sant'Antioco is the island's largest settlement. It is also the site of ancient Sulci, considered the second city of Sardinia in antiquity.

The Archipelago of Sulcis (in Italian Arcipelago del Sulcis or Sulcitano) is located off the coast of Sardinia, and is part of the disestablished Province of South Sardinia. The archipelago is 160 square kilometres (62 sq mi) in land area. The region had a resident population of 19,345 in 2022.

Many of the inhabitants are descended from the Ligurian inhabitants of a Genoese coral-fishing colony established in the 16th century on the Tunisian island of Tabarka. Following the capture of Tabarka in 1741 by the Bey of Tunis they fled the island and, with the permission of Charles Emmanuel III of Sardinia, settled the islands of Sulcis. The Tabarkan settlers established the towns of Carloforte on San Pietro Island and Calasetta on Sant'Antioco. The residents of these areas speak the Tabarchino dialect of the Ligurian language, which is recognized as a minority language by Sardinian regional legislation.
