The Torre di Ligny stands at the extreme western point of the Trapani peninsula, a massive 17th-century Spanish fortification built to defend the tip of the headland. The tower now houses a small museum of prehistoric finds from the surrounding area — flint tools, pottery, and objects from the Sicilian Bronze Age — along with a section on the history of the sea floor around Trapani, where wrecks from the First Punic War (particularly the Battle of the Egadi Islands in 241 BC) have been found in exceptional preservation.
The real reason to come here is the location itself: the tip of the peninsula with open sea on three sides, the Egadi Islands visible on a clear day to the west, and the salt pans stretching south toward Marsala. The wind is usually strong. The light in the afternoon, when the western sun catches the white salt crystals in the pans, is exceptional.
