Kohren Castle, also known as Chorun or Sahlis, is the ruin of an imposing hill castle in the town of Kohren-Sahlis in Leipzig county in Saxony.
The origin of the town Kohren can be traced back to the time of the Sorbian settlement in the Early Middle Ages. Emperor Otto II gifted the forest between the rivers Saale and Mulde to the Bishop of Merseburg in year 974.
The castle was owned by Kohren family from the late 12th century, but i was destroyed in 1220 during local wars. The current towers were built after that, but it was again demolished during the mid-15th and 17th centuries.
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.
