Château de Buchenek is a castle in the commune of Soultz-Haut-Rhin. Dating from the second half of the 13th century, it was altered, possibly in the 14th century, and in the 16th century.
The castle was first recorded in 1251. The logis, of a rectangular plan, possibly still dates from this period at the lower level; it was altered in the 14th century (there is evidence of building work) as well as in the second half of the 16th century (staircase tower). Restored after the Thirty Years' War, the castle was sold as national property. In the 19th century it was used as a factory. Bought by the town in 1976, the castle has had a significant restoration and, since 1990, has housed the municipal museum.
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.
