The Château du Grand-Geroldseck is a ruined medieval castle situated in Haegen, Alsace. The castle is one of the oldest in the northern Vosges, founded at the beginning of the 12th century by the lords of Geroldseck, avoués of the abbey of Marmoutier, to ensure the protection of its territories. It constitutes a fine collection of feudal residence. Built on a platform, it combined the functions of dwelling and defence. It was heavily altered at the 13th, 14th and 15th centuries.
The square keep has walls three metres thick, faced in embossed stone. The cellars of the lord's residence and the barbican are still visible.

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.
