Mining began in Cunersdorf in the 16th century. Due to its high yields, the mine quickly gained renown. From 1536, a yield of 2,409 guilders per share was achieved within two and a quarter years. This was primarily due to a very rich silver ore vein with silver contents of up to 40%. However, yields declined again in the following years.[2] During the sinking of a pilot shaft, the year 1551 was discovered at a depth of more than 125 m.[3] The current entrance to the Dorothea adit was created in 1853.[4] Initially, only silver ores were mined; later, nickel, copper, uranium, and cobalt ores were added.[3] After the Second World War, in 1946/47, the SAG Wismut began searching for uranium in Annaberg-Buchholz, including in the Himmlisch Heer Dorothea mine. Uranium mining was short-lived and ended in 1958. Source: Wikipedia

We now walk through the valley, with the rocks rising up beside us. At the side of the path, we find the entrance to the Tiefen Blühend Glück tunnel. https://youtu.be/LYmwgx7Z0Lk

definitely worth a trip

Pleasantly cool in summer.

Great guided tours, highly recommended. ⚒️

what you can discover here ;-)

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.

The tunnel was excavated between 1855 and 1886. However, enough was never really found here and so it only leads a little more than five hundred meters into the mountain. However, the beautifully brick mouth hole that can be seen today was once destroyed when the keystone was stolen. After the fall of the Wall, the Pobershau Mountain Brotherhood renovated it. The tunnel now also serves as a roost for bats. Source: https://www.ins-erzgebirge.de/Mundloch-des-Tiefen-Bl%C3%BChend-Gl%C3%BCck-Stollns
