"Luck on the building to God in the Gaisberg"
The search for mineral resources in the Swabian Forest stopped a long time ago. But a hike to the historical places of the "silver rush", which was triggered by alleged silver finds in 1768 and encouraged by the Murrhardt prelate Oetinger, is even more worthwhile today.
The search for coal and silver is part of the eventful industrial history of Spiegelberg. The hope for quick fortune attracted adventurers and dubious entrepreneurs.
Tunnels were created and new donors were repeatedly found, but there were no successes.
Johann Kaspar Schiller was among the donors. Since he had invested and lost money in the silver mine, "Spiegelberg" in the Schiller household was not associated with good memories.
Probably because of this, son Friedrich called the worst villain "Spiegelberg" in his play "The Robbers".
The tunnel is about 22 m long. To protect the bats that live there, it was fitted with a protective grille.
