The Château du Nideck is a ruined castle located in the commune of Oberhaslach. Situated on the heights of the road from Oberhaslach to Wangenbourg, the castle was first mentioned in a charter in 1264, as the property of sire Bourckard, burgrave of Nideck. In 1336 there is mention of a second castle, below the first, fief of the Bishop of Strasbourg and held by the landgraves of Basse-Alsace.
Nideck then became the property of the seigneurs of the region, in the 14th and 15th centuries, according to the various regional conflicts and other events of the time. It was besieged by the Strasbourgeois in 1448. The Müllenheim family took possession of the castle and kept it until 1509. It was finally destroyed by a fire in 1636.
The castle overlooks the Nideck waterfall and is easily reached on foot. The castle has been listed since 1898 by the French Ministry of Culture as a monument historique and is owned by the state.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
