The Château d'Andlau is a medieval ruined castle. Constructed on a narrow granite outcrop which dominates the valleys of Andlau and Kirneck. The castle was built from granite blocks, certainly by Eberhard d'Andlau between 1246 and 1264. In 1678, after the joining of Alsace to France, it was pillaged by the troops of maréchal de Créquy. The castle stayed in the hands of the Counts of Andlau until the French Revolution and served afterwards as a residence for a gamekeeper in the service of the family.
Confiscated as a national asset, it was sold in 1796 to a merchant who, from 1806 and, with no apparent public opposition, began to sell the castle piece by piece. In 1818, Antoine-Henri d'Andlau bought the ruin and saved it from destruction. Repair work was carried out in 1856. It still belongs to the Andlau family.
The castle is on two levels. The higher part is built on a narrow ridge approximately 25 m wide and 80 m long, orientated south-south-west to north-north-east. It consists of a long residential building flanked at each end by circular towers about 10 m in diameter. The castle was built in one piece; only the lower court has been altered (in the 16th century). Like the neighbouring Château du Spesbourg, the building material was granite excavated on site. To the east, a steep mountainside provides a natural defence while on the other sides, a wide, deep moat cut into the rock isolates and protects the site.
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.
