Very interesting Jürgen, thanks for sharing!
Eventhough i mainly roam the Northern parts of Germany when visiting, as the border merely is a 3 hour drive away from me, i have considered "diving deeper" for more exploration.
This place definitely will be kept in mind as a point of interest...especially after seing that is as close to Lüdenscheid as it is, could be a fine chance to kill two birds with one stone
