South of Lengenfeld unterm Stein, in the Dünberg, in the upper third of this shell limestone mountain, lies the so-called human cave, a typical demolition crack cave in the shell limestone. It was probably mentioned as early as 1630-1632 and surveyed in the GDR in 1987. The mouth in the form of a mountain crack is located in a small ravine or in a ditch, after which the cave probably runs predominantly vertically.
Unfortunately, the man cave is a bit difficult to find (depending on how you look at it). The signpost disappeared a long time ago. If you still want to go there, look out for the beech tree with the blue letters MH.
