Kohren Castle, Castle ruin in Kohren-Sahlis, Germany

Kohren Castle, also called Chorun or Sahlis, is a hill castle ruin on the Burgberg in Kohren-Sahlis, Leipzig county, Saxony. Only the two bergfried tower ruins with high entrances and parts of the perimeter walls remain, shaping the town's silhouette. The west tower was built first, and about 50 years later a second bergfried was added.

Kohren is first mentioned around 1010 in Bishop Thietmar of Merseburg's chronicle, who stayed there for ten days in 1018. In 1190 the lords of Kohren held the castle; after they sided with Leipzig in 1216, Margrave Dietrich of Meissen ordered its destruction in 1220. It was rebuilt by 1240, and the visible masonry dates from this phase. The lords of Einsiedel abandoned it in the 15th century, and by 1568 it was described as desolate.

The name Kohren goes back to the Sorbian settlement of the early Middle Ages; the castle was also called Chorun or Sahlis. Bishop Thietmar of Merseburg stayed here in 1018 for ten days and confirmed the people who came to him. A legend links the castle to Kunz von Kaufungen, who is said to have stayed here the night before the 1455 kidnapping of the Saxon princes.

Visiting requires sure footing, as steep paths and uneven terrain make some areas challenging to reach. Wheelchair users should check on site which areas are accessible, since most sections lack accessible pathways.

A local legend claims that Kunz von Kaufungen stayed at the castle the night before he abducted the Wettin princes in July 1455; after his execution the castle was said to have been razed to erase his memory, though no evidence supports this. The last castle house was demolished in 1900.
