Bergwerk Bierfincksgraben

It is actually surprising that the topic of "dry wall" is the subject of an information board, while a little off the hiking trail at the end of a path a tunnel opens up that leads to a widely branched mine.
In addition to protecting the bats, this may also be the reason why a grid prevents further access after about 10 meters. From here, however, you can already see numerous tunnels leading downwards, upwards and to the side, which are only poorly secured or not secured at all, so that one can quickly sink into the bottomless holes filled with water. Exploration would be exciting but potentially very dangerous.The wood found in the Bierfinckgraben mine allows the mining activity to be dated to three periods around 1500, around 1700 and 1750.Literature:
