Castles
Arab-Norman castle
The castle has a trapezoidal plan with a rectangular courtyard, three corner towers and a fourth taller and more imposing cylindrical tower that guarded the valley below towards the south-western coast of Sicily.
Some of the wall structures, which are partially extant, formed part of the city wall circuit. The only remaining traces of its gates are in place names, such as the nearby Via Porta Gibli.
