Rocca, a medieval castle with quadrangular bastions bounded by a canal with drawbridge, was built in 1124. It was the fortress of the noble family Scaligeri, who became the Lords of Verona. It was rebuilt several times and it was used by the Austrians as barracks in the 18th century. It is frequently the seat of cultural activities, especially during the summer months. It hosts the Civic Museum and of the Picture Gallery.
References: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.
