The Château de Tardes was built between the 13th and 14th centuries as a medieval stronghold, but was converted in the 16th century to a Renaissance-style mansion, with the addition of mullions and a troubadour-style hexagonal tower with a spiral staircase. The building is not open to the public.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
