The castle of Salemi is one of the best preserved castles in Sicily. Inside, the library and the resurgence museum are housed. The castle has Norman origins and dominates the town with its trapezoidal shape and square, 20 meters high, corner towers, and a cylindrical tower.
The castle was built by Norman King Roger around 1077 to the site of Roman-Arab fort. Frederick II altered it in the 13th century.
In 1441, on December 11, in the castle of Salemi a confederation made up of Salemi, Trapani, Mazara, Monte San Giuliano and by the barons of Castelvetrano and Partanna was formed which undertook the defense, and bore the costs, of the Queen White and Royal House of Aragon. Salemi was, therefore, more fortified and garrisoned during the raids of the Turks.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
