Hesperange Castle probably dates from the early 13th century when the Counts of Luxembourg gave Hesperange to the Lords of Rodenmacher who sided with the French when the Burgundians conquored Luxembourg in 1443. Maximilian of Austria dismantled the castle in 1480 and 1482 after battles with Gerard of Rodenmacher. In 1492, he transferred it to the Lords of Baden who had to pawn it in 1692 and could only reclaim it in 1740.
After the French captured the castle in 1796, the French government nationalized it and sold it by auction in 1798. Later parts of the ruins were sold individually and by 1820 seven houses stood on the castle grounds. Now a national monument, the ruins are still privately owned.
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.
