Here you are in the relics of an old medieval tower hill castle of the Fürstenberg, which was surrounded by a wall and moat and has a cistern approx. 2.80 m deep. The facility is one of the largest in the district. There is an information board on the wall.
During archaeological investigations in 1989, a wall was uncovered, which suggests an approx. 20 m long building: a square, specially surrounded by a wall and a ditch, the permanent house of the mining manager.
The entire mining area, approx. 10,000 m², has numerous pings and the former position of pit houses is recognizable.
This area is heavily fractured and has three large pings overlying the Martin-Römer adit and several small pings and heap-like elevations. In the north-west corner of the area there is a separately walled area of 15 m by 20 m, in which archaeological investigations have revealed the remains of a sunken building (pit house) and ceramic fragments.
