The Michalowice Chamber is located 109 meters underground. It is of a unique character because of its size.
This huge, 35-metre-deep cavern is filled with a complex wooden scaffolding, erected in the 19th century with no help from any machinery, piece by piece as the vertical lode was excavated.
This deposit was so huge, it was exploited for almost a hundred years!
The chandelier is made of salt crystals.
