During the middle ages up to the early 19th century, the Langenberg was completely cleared from any forests. The Langenberg originally belonged to the villages of Schlewecke, Harlingerode, and Göttingerode. However, since Göttingerode was given up in the 15th century, a dispute between Schlewecke and Harlingerode arose over the former community land, eventually being successful for Harlingerode.
