Filseck castle dates from the first half of the 13th century when it was built by Counts of Aichelberg. In 1596 it was acquired by Burkhardt von Berlichingen, who built a Renaissance castle with two towers. The ornamental paintings in the hall dates from this period. A devastating fire destroyed the south and west wings of the castle in 1971, but the restoration completed in 1994. Today Filseck castle hosts cultural events, such as concerts and exhibitions.
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.
