The current Autelbas castle was built in 1432 on the ruins of the old castle from the 13th century (destroyed in 1412 by the Burgundy army). In 1983, Autelbas Castle fell victim to a large fire and burned to the ground. It has been a ruin ever since. The last decade there have been some consolidation campaigns but it is clear that it still needs some considerable restoration works for it to survive.
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.
