Hasestollen

From 1856, the tunnel connected mining in the north of the Piesberg with the lower area in the south of the mountain, where the newly built colliery station was put into operation the following year.

The Hasestollen was not only used to extract coal. The mine water from the entire colliery was also drained here to the River Hase. However, the salty water led to considerable environmental problems, so the mine was closed as early as 1898. The Hasestollen was then used once again as an air raid shelter during the Second World War.

The Museum of Industrial Culture Osnabrück had the tunnel excavated from 1997 and opened part of the shaft and an approx. 300 m long accessible tunnel in September 2000. It leads from the Haseschacht building, where the permanent exhibition is located, to the magazine (special exhibitions) and horse stable (museum education) as well as to other museum buildings.
