Province of Trapani
The island of Favignana ("Aegusa"), the largest, lies southwest of Trapani; Levanzo ("Phorbantia") lies west; and Marettimo, the ancient "Hiera Nesos", west of Trapani, is now reckoned as a part of the group. There are also two minor islands, Formica and Maraone, lying between Levanzo and Sicily. For administrative purposes the archipelago constitutes the comune of Favignana in the Province of Trapani.
