Centre Charlemagne is the new museum of Aachen local history. It occupies the site on the Katschhof, the former palace courtyard. It focuses on a history of Aachen from the Neolithic to the present day. The key periods are the ancient Roman age (until 4th century AD), Charlemagne's Aachen (the capital of Frankish Empire), the medieval period and Baroque period. The whole house is barrier-free.
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.
