The island of Favignana, the largest of the Egadi Archipelago, is called “the butterfly" (with spread wings) because of its peculiar shape, divided into two parts by the hill of Santa Caterina.

Known as Aegusa by Greeks, then it changed its name to Favignana for the Favonio wind, which always blows there, making its climate mild and fresh. Nowadays, the municipality, which is part of the district of Trapani, has about 4,383 inhabitants.
