If the sign did not point to the remains of a stalactite cave, you would have no idea what you were looking at here... very inconspicuous

A really worthwhile mine trip by mountain bike to the Merkers potash mine. The tour offers a lot of interesting things and things worth seeing. For example, in the large bunker you can find the largest shovel excavator ever used underground. In the gold room we were also told a lot of interesting facts about the treasures of the German Reichsbank that were stored there during World War II. And the crystal grotto at a depth of 800m is a real feast for the eyes. But the best thing about it were the prevailing temperatures between 21°C and 28°C, even during our visit in December.

Unfortunately, it has now dried up. Only fragments of the stalactites can be found.

A concert at a depth of 500m is a great experience and will definitely not be the last. Starting with the long queue at the entrance, the journey continues with the conveyor cage (approx. 8 meters per second) and then with the team car to the deepest and largest concert hall (Wikipedia) in the world.

For the "temporary miner" the experience in Merkers begins with the rope ride, which takes him - well equipped with helmet and headlamp - to a depth of 500 meters in 80 seconds. Now the mine trip begins: It leads over around 25 kilometers of the 140 square kilometer mine field and conveys a special form of group experience in the winding, often dark stretches several hundred meters below the familiar surface. Qualified miners accompany you through a total of six stations, impart a lot of interesting information and can also share some anecdotes. The explanations are tailored to the individual interests of the visitor groups. Source and more information: https://www.thueringen.info/erlebnisbergwerk-merkers.html

Inconspicuous, with the wooden gate around it, you drive past it quickly.
