Like a mighty tower, the round Radstube is rooted in the soil. The deepest point 24 meters below the surface is where the mighty waterwheel was located to facilitate the drive of the hoisting equipment.
The Radstube which is, in view of its size and design, unique in Europe, can be visited through a bold staircase construction. Right beside it but completely underground is the oval-shaped vaulted Radstube, which is 15 meters high and hewn with natural stone. Contemporaries describe it as “the most beautiful of the whole Harz”. The enablement of visiting the Radstube ranks among the coming tasks in the World Heritage Upper Harz Water Management.
