The Romans called it Ustum, 'burnt', because of its volcanic origin; the Greeks Osteodes 'Ossuary' for the human remains of Carthaginian mercenaries. It may correspond to Eea, the city of the sorceress Circe in the Odyssey. Ustica is shrouded in charm, history, and unique landscapes.

Ustica is an Italian municipality that coincides with the island of the same name, which, belongs to the area of the metropolitan city of Palermo, from which it is about 65 kilometers away. Ustica can only be reached by sea as it is a spur of land and rock 8.5 kilometers long that corresponds to the emerged part of Mount Anchise.
