Gläserstolln

The glass tunnel in the Hüttengrund is a testament to the early years of Marienberg mining and was built in 1523 as a hereditary tunnel to drain the Marienberg central district. At that time it was the deepest tunnel south of Marienberg with a length of 3.5 km. The name was probably given by the local Brille family, who were closely linked to the Marienberg mining industry through Dominicus Brille. The Brillestollen was a hereditary tunnel and was entitled to the “Ninth of the Tunnel”, a levy from all mines, which, as the deepest tunnel, saved the costs of raising water. Its mine water was used to operate the lower Marienberg smelter.When mining came to a complete standstill in Marienberg at the beginning of the 20th century, the mouth of the Glass Tunnel was filled with rubble stones in 1907 to 1908 as part of the preservation and security work. The first excavation work began in 1994 through the initiative of the Marienberg mining association. Since then, many interested visitors have been welcomed to the Brillestolln by members of the Bergknappschaft Marienberg e.V. Unfortunately, after renovation work by the mountain safety team, the Brillestollen is no longer accessible to the public. Today it only serves internal club purposes.
