A fenced area where slate was formerly mined. Is privately owned

Very interesting

Between 1627 and 1858 the tuff in the Krufter Bachtal was mined by underground blasting, which is evidenced by boreholes in the walls. The definition of the period is based on the following facts: The use of blasting technology in European mining was first documented around 1627. Because of the dangers, underground tuff extraction was banned in 1858. For mining, a good 3 meter wide corridors were driven into the stone at a depth of about 15 meters. The distance between the aisles was about 20 to 40 meters. A rectangular underground tunnel system of approx. 250 m × 150 m was created. The blasting had already broken the tuff into smaller pieces. Crushed again by hand, the stones were stacked on arks for days. After a drying time of about 2 weeks, the stones were ground into fine rock powder, into trass. Trass has hydraulic properties and was used in conjunction with lime to create a waterproof mortar.

In the Roman mine in Meurin you descend into the subterranean working world of Roman miners and soldiers. Flashlights are not needed - modern pumice mining has uncovered the ancient quarry. Large parts of the old mine cover have now disappeared. Easy-to-walk footbridges, ramps and stairs not only lead the visitor through the tunnel system, but also beyond it. So it is probably the only mine that you can see from a bird's eye view. Once covered by a meter-thick layer of pumice, the 1,700-year-old tufa tunnels and shafts are now protected under the cantilevered hall construction of the Meurin Roman mine. The original traces of mining by the ancient Romans, large illuminated images, exciting exhibits and a film in the cinema gallery bring the dusty and hard work underground to life again.

There is always something to explore.

Unfortunately, the tunnel cannot be visited

Valuable slate that had not yet been exposed to wind and weather was once mined here in the tunnel. Nowadays, a grille prevents people from entering the tunnel. But bats can count themselves lucky, because this measure has given them a home.
