Hall Stein Hill is located in the city of Kassel, and it extends at an altitude of approximately 476.6 meters above sea level. The hill is characterized by the abundance of its perennial natural trees that have lived for thousands of years. The hill also contains metamorphosed basalt rocks and the ruins of the famous Hall Stein Monastery, which was standing on top of this hill since time immemorial, but due to natural factors it has become today in ruins.
