The Château d'Usson is one of the so-called Cathar castles located in the commune of Rouze. It is sited upstream from Axat, along the Aude River gorge, carved out of the foothills of the Pyrenees.
The castle dates from the 11th century (perhaps earlier) and during the Cathar period marked the eastern boundary of the territories of the Counts of Foix. In the 12th century, this was the capital of the Donézan region. Before the défilé was cut through the mountains to link Quillan to Axat, this was an inaccessible outpost providing succour for faidits and other persecuted Cathars. The Cathar bishop of Toulouse Guilhabert de Castres is known to have taken refuge here.
Towards the end of the wars against the Cathars this was one of their last sanctuaries, providing support for Montségur. The seigneurs of Usson, Bernard d'Alion, lord of the Château de Montaillou, and his brother Arnaud d'Usson sent arms and supplies to their besieged comrades there. On 15 March 1244, the day before 225 Cathar parfaits were burned alive at Montségur, four other parfaits left the castle there for Usson, where the Cathar treasure had been evacuated a few months earlier. This mystery has fed a number of theories about the equally mysterious treasure supposedly found at Rennes-le-Château in the 19th century.
Bernard d'Alion was burned alive at Perpignan in 1258. The castle was rebuilt as a French border fortress, and given by Louis XIV to the new Marquis d'Usson. Like other seigneural residences it was sold as communal property at the French Revolution, after which time it was used as a stone quarry.
On display at the castle are parts of the wreckage of a Second World War British Dakota transport aircraft which crashed on 5 December 1944 on a nearby mountain with the loss of seventeen lives.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
