The Chateau de Caradeuc was built in 1722 by Anne-Raoul Caradeuc de la Chalotais. It is most famous by its gardens, built in the 19th century on the woodland hills of Bécherel in the formal French style. Gardens were designed in 1898 by Edouard André. Decorated with many statues the gardens offer a spectacular panorama over the high valley of the Rance. They are open on weekends and bank holidays in May, June and September.
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.
