The Château de Ramstein is a ruined castle in the commune of Baerenthal. This 13th-century castle was built by the lords of Falkenstein on the instructions of the bishop of Strasbourg to control the Zinselbach valley, probably in 1292. During the course of the 14th century, the lords of Ramstein transformed it into a den of brigands and it was destroyed in 1355 during a punitive expedition by the Strasbourgeois and their allies from Bern.
Below the castle can be seen two underground passages dug in 1936 by French military engineers as part of the Maginot Line. They were used as shelter by the local population during the battles of winter 1944-45. This site is currently closed to protect a colony of bats.
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.
