Heimburg castle was built from 1294 on as a bastion in the Electorate of Mainz against the Palatines. It decayed later and was destroyed by the French in 1689. In the 19th century it was rebuilt by the industrialist Hugo Stinnes.
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.
