The Karlsstollen is not at this location. A signpost on the hiking trail says it is about 400 m away, but I haven't been there, otherwise I would have reported it to the "editors".

Nice place for a short break 🥪🥤

How to get there: If you take Malberger Straße in the direction of Holzhausen, the Malberger tunnel is on the left-hand side directly behind the Georgsmarienhütte municipal works building (Malberger Straße 13). The tunnel is difficult to see from the street. The tunnel can only be reached on foot. Along the wooden railing, a small path leads down to the tunnel entrance.

It was intended to open up the still existing and, as was initially assumed, very productive coal deposits from below Oesede to Borgloh and at the same time drain off the mine water. Of the estimated total length of 6740 m, however, only just under 3000 m were completed. The tunnel initially runs straight from the Malberger Mühle in an easterly direction along the southern slope of the Osterberg, then bends several times, drives under Osnabrücker Straße in Oesede am Knapp and ends 150 m north of the local train station in the valley of the Gartmannsbach. The high expectations that had been attached to the expansion of the tunnel were not fulfilled. The low thickness of the seams and their poor storage meant that profitable mining of the coal did not appear worthwhile. The ambitious tunnel project ended in 1853 after six years of construction.
