The Abbey of La Clarté-Dieu was a Cistercian monastery. The abbey was founded in 1239 by the executors of Peter des Roches, Bishop of Winchester, as one of a pair, the other being Netley Abbey in Hampshire, England. The bishop had conceived the idea of founding a pair of monasteries some years before and had begun collecting the necessary endowments for them, but his death in 1238 prevented him from completing the project. The first monks arrived at the site in 1240.
The abbey was severely damaged in the course of the Hundred Years War and the cost of rebuilding proved a heavy burden on the finances of the community. Nevertheless, La Clarté-Dieu managed to survive until the French Revolution when it was closed and sold off along with all the other monasteries of France. Following the revolution the abbey was for a long time used as a farm and some of the buildings were allowed to fall to ruin. Despite this, much of the mediaeval abbey remains in excellent condition along with some fine post-mediaeval additions. The abbey is preserved as an historic monument and is open to the public.
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.
