The name of the hill comprises two parts: Kollwess and höh.The first stems from the fact that the land on which the hill lies used to belong to the Kohlwes family in Wehdem. The second part is related to Höhe, the German word for height. As a result of transcription errors between maps in the 19th century there were various versions of the name, but eventually the name Kollwesshöh was settled on.
