Location and access

Calasetta occupies a coastal position on Sant'Antioco, an island connected to the Sardinian mainland by a causeway that makes the town accessible by road from the Sulcis region. The town has a small harbour and marina serving fishing boats and leisure craft and providing links to nearby islets. Road connections, seasonal ferry services and local boat traffic support both everyday life and tourism.

History and language

The modern settlement was shaped by colonists who arrived from the Genoese colony of Tabarka in North Africa in the 18th century. These settlers brought a Ligurian-derived dialect, locally known as Tabarchino, which survives alongside Italian and Sardinian in speech, family names and local customs. Historical memory and family traditions preserve this distinctive cultural layer within a broader Sardinian context.
