Wildenstein Castle consists of a residential and fortified tower. Unlike other castles of its kind, the tower remained intact after losing its military and residential functions in the 15th and 17th centuries. The history of castle dates back to the 13th century. In 1293 Heinrich von Eptingen took the name von Wildenstein. Under his son Gottfrid Wildenstein defended the castle against the the Bern and Solothurn armies in 1334. In 1995, the canton of Basel-Landschaft acquired the Wildenstein, and today there are regular cultural events.
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.
