Lighthouse restored in 1979
Ligny tower stands on one end of the city, on a rocky cliff above the ocean. It was constructed to defend the coast from attacks by Turkish pirates in 1671, but also worked as a lighthouse. The architect was Charles Grunembergh, under the command of the Spanish Viceroy Don Claudio La Moraldo (Prince of Ligny). It is square shaped and constructed with stone. It overlooks the city and is characterized by a tiny door, on which there is a window and a coat of arms. After World War II the tower was abandoned, and in the year 1979 it was restored by architect Francesco Terranova. Since the year 1983 it has been home to the Museum of Prehistory and Archaeology Marina Trapani, which can be visited from 9 to 13 and from 16.30 to 19.30h (entrance fee is € 1.50).
