The Frohnau mining landscape is an expansive area of heaps with small deposits from the 15th to 17th centuries, which follow the underground ore veins, larger main shaft heaps from the 18th century and large heap deposits from the period of uranium ore mining. The surface buildings that originally belonged to the shafts have not been preserved, with the exception of the area around the Malwine mine and the Markus Röhling mine. The Markus Röhling visitors’ mine can be accessed through the opening of Adit 81. South of this opening the adit’s actual opening can be found. It stretches over a total of approximately 8.6 km.
