Château de Saint-Félix-Lauragais was originally constructed in the 11th century. The first Synod of the Cathar church, known as the Council of Saint-Félix was held there in 1167. In the 14th century, the castle was transformed into a country house by a brother of Pope John XXII. The complex includes buildings from the 13th to the 18th centuries.

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.
