Blankenhain Castle is a large castle in Blankenhain near Crimmitschau. The castle dates back to the 12th century. It is first documented in 1423 as Wasserburg. Half of it burned down in 1661 and was rebuilt in 1699 (some sources say 1700). In 1765 the castle acquired its current Baroque appearance with mansard roof and domed towers. After World War II, the Soviet regime ordered the castle destroyed, but it was saved by the intervention of courageous locals. Since 1981, the castle and the surrounding land have been developed as an open-air museum of agriculture and rural life in central Germany between 1890 and 1990. The museum covers 11 hectares, including 60 buildings.
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.
