County of Klettenberg
The county of Klettenberg was an area in the southern Harz and its foreland. Its administrative center was originally the Klettenberg Castle in the town of the same name between Bad Sachsa and Nordhausen .
The Klettenberg Castle was probably built around 1087. The first mentions of the County of Klettenberg go back to 1187. From the Emperor Friedrich I (called Barbarossa) Konrad von Ballhausen was enfeoffed for his services with the county. He is considered the lord of the Counts of Klettenberg. They were wealthy in numerous places in the Golden Aue, the places Branderode and Neuendorf they owned completely as after-fiefs of the Counts of Orlamünde. The Counts of Hohnstein fought the Klettenbergs in the 13th century and incorporated the County of Klettenberg into their own county in 1253.
In 1593 the county came to Braunschweig-Wolfenbüttel , in 1634 to the Halberstadt Monastery and in 1648 in the course of the Peace of Westphalia to Kurbrandenburg . After the county fell to the Kingdom of Westphalia in 1807 , it belonged to the Nordhausen district . In 1814 it became Prussian again and together with the County of Lohra formed the Prussian part of the County of Hohenstein.
Sparse ruins of Klettenberg Castle, which was destroyed by the Harz riflemen in 1627 , can still be found today.
