The first records of mining activity in the Luckenbach district date back to 1685/1686. The Edelstein brown iron ore mine runs from the tunnel entrance in the Hardt area, approximately 220 meters northwest, and was operated until around 1922, but became uneconomical. At the end of World War II, the tunnel served as an air-raid shelter. While the men were at war, the population, mothers and children, had to take refuge in the tunnel when air raid warnings sounded. Nowadays, however, only part of the mine is accessible due to overburden deposits. For safety reasons, a solid door was installed in the entrance area. From time to time, guided tours of the mine are offered, which I highly recommend.

Former Edelstein ore mine. The former mine, whose tunnel mouth was reopened in 1991, is located in the Luckenbach district. It was apparently an underground mine operated by hand, as the first information from 1860 suggests. The ore was mined here between 1844 and 1920. The tunnel can also be visited.

Information about the Edelstein mine: https://www.luckenbach-ww.de/gemeinde/grube-edelstein/ From Easter Monday to the end of October, the "Grube Edelstein" is open to visitors every second Sunday of the month without registration. Currently (4/2024) guided tours take place from 2 p.m. to 5 p.m. (from 3 p.m. to 6 p.m. the village café in the nearby Backes offers coffee, cake and drinks, highly recommended!) The tunnel leads about 100 meters into the mountain, widens in the rear part and branches off into outgoing tunnels. A water-filled shaft leads into the depths to lower levels.
