Châtelard castle was built probably by Rudolph Grossi, bishop of Aosta in 1243 and archbishop of Tarantasia in 1246. It is first mentioned in a document from 1248, and presents the type of circular tower reminiscent of the fortified constructions of Count Peter II of Savoy, to whom Grossi was a close advisor. All around, medieval dwellings of all shapes and sizes dot the land like small sentries with an ancient charm: the Pascal fortified house, the Aragon fortified Manor house, Maison Gerbollier, just above, the home of the Ecours and again, in the village of Derby, the notarial castle.
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.
