Isolotto Formica Lighthouse

Isolotto Formica Lighthouse is an active lighthouse located on an islet, 302 metres (991 ft) long and 206 metres (676 ft) wide, at 4 nautical miles from Trapani in western Sicily on the Sicily Channel. The island is dominated by a quadrangular fortification, built by the Pallavicino in the mid 1600, and a Tonnara, built by the Florio in the mid 1800, which was closed in 1979. From the 1980s the island is a private property belonging to Mondo X which is involved in the recovery of drug addiction.
