History
The area was inhabited from pre-Nuragic to Roman times. In the Byzantine period monastic communities settled here, documented from 1066. It passed to Pisa in 1258 and to Aragon in 1355; under Spanish rule it became a county and then a marquisate. In 1793 French troops landed here and were driven back. In 1853 Palmas became a municipality and, after several name changes, took its current name in 1950. The Monte Pranu dam led to old Palmas being abandoned and rebuilt nearby.
What to eat and buy
The local economy is based on farming and herding: vegetables, olive oil, cheese and Carignano del Sulcis wine. Festive sweets include piricchittus, glazed pastry balls, and pistoccus de crobi.
