Isolotto Formica Lighthouse, Maritime lighthouse on Formica Island, Sicily, Italy

Isolotto Formica Lighthouse is a cylindrical concrete tower on an island off Sicily with a white exterior and grey lantern dome at its top. The structure rises about 20 meters and sits surrounded by water, making its role as a navigation aid for ships clear.

The lighthouse was built in 1858 by the Genio civile under the Kingdom of the Two Sicilies, on the north-eastern bastion of the quadrangular fortification raised by the Pallavicino family in the mid-1600s. The islet lies 4 nautical miles from Trapani, in the Sicily Channel, and belongs to the comune of Favignana. A Tonnara built by the Florio family in the mid-1800s closed in 1979; since the 1980s the island has been private property of Mondo X.

The island was once a center for tuna fishing operated by the Florio family, an activity that continued until 1979. This maritime heritage remains visible in the landscape today.

The lighthouse is fully automated and managed by the Marina Militare, with identification code 3128 E.F. It stands on the north-eastern bastion of the fortification, and its light is 28 metres above sea level. The islet lies 4 nautical miles from Trapani and is private property, so landing is not permitted.

The island is now managed by Mondo X, an organization supporting individuals recovering from drug addiction. This gives the historic location a second purpose as a place of rehabilitation and hope.
