The Château de Dreistein is a ruined castle in the commune of Ottrott. It is, in fact, three separate castles built on rocky promontories, hence the name drei Stein, 'three stones' in medieval German. It was built in the 13th or 14th centuries and was separated into two sections later. In the 17th century it was destroyed.
The castle is sited on the massif of Mont Sainte-Odile, to the west of the abbey. It overlooks the valley of the Ehn which it controls along with the castles of Koepfel, Rathsamhausen and Lutzelbourg and the Château du Hagelschloss. As with the latter, it is close to the Pagan Wall of Mont Sainte-Odile.
In common with all the neighbouring castles of its time, the castles at Dreistein are constructed from pink sandstone from the Vosges. The remnants of the two castles are separated by a ditch. The western castle is flanked by a half open staircase tower.
Access to Dreistein is only possible on foot, following paths laid out by the Vosges Club.
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.
