Elewijt Castle originates from the 11th century when there was a wooden fortification. The stone castle was erected around 1300. The castle is also known as Rubenskasteel because it was owned by Peter Paul Rubens from 1635 to his death in 1640, and features in some of his paintings. In 1792 the castle was converted into a state prison. Nowadays, the castle is privately owned, not open for visits but rented for 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.
