You can get to know the galleries in a different way - and capture them
photographically. First, you walk through our underground illuminated exhibition with the
historical reconstructions and the partly very impressive mining machines.
Then we head to the unlit part of the mine "Langengrund" with its old substation and the underground air compressor room of the mine HADIR-Langengrund. There you will find almost everything as it was left behind in the 1960s.
You have time to explore the respective mines on your own and a guide is on hand
to answer any questions.
