Farmer makes amazing discovery on his farm - authorities send cave explorers. Under an old concrete floor he comes across something unexpected.

The preserved tunnels are 16 meters long, equipped with a round arch profile and 15 lamp niches. Underground tunnels probably served as a hiding place from robbers. Only 50 of these secret passages are known in Lower Austria. Six of the “earth stables” are currently open to the public. Police investigated after a spooky discovery in a wooden box in a house in Sweden.
