In the back of Joergesov dom is about 80 m reconstructed mining tunnel Sabina, which is available to the public. For reasons of safety, the visit of the gallery is possible only with responsible person of Joergesov dom.

Gallery illustrates how the history of the townhouses were created, some them for a search of gold, copper, silver and also as a escape corridor for the residents of these buildings.

Before entering the tunnel, there is restored cellar with vaults made from stones.
