VIIth Shaft of the Rothschönberg Drainage Tunnel

The seventh light hole in the Rothschönberger adit (123 m) was powered by hydropower from the Mulde. Greenhouse, Radstuben (chew not preserved), Bergschmiede and Pulverturm are identical in construction to the IV. Lichtloch. The heap was reshaped by later mining activity of the pit Aid. The association VII. Lichtloch des Rothschönberger Stollns e. V. operates the facilities and opens on certain occasions. (siebentes-lichtloch.de/).

The Rothschönberg tunnel is the deepest and longest water release tunnel in the Freiberg mining area and is part of the Krušnohoří Ore Mountains UNESCO World Heritage Site. It was built in 1844-1877. The fiscal (state-financed) part has a length of 13.7 km from the Röschenmundloch in the Triebisch near Rothschönberg to the VIII. Lichtloch in Halsbrücke and an increase of 0.032%. For this purpose, 8 light holes were sunk and the adit was excavated in on-site operation with a width of 2.5 m and a height of 3 m. In the mining area to Langenau (Frankenschacht) there are still a good 15 km of main adits (including Reiche Zeche, Drei-Brüder-Schacht), with side adits to Zug and Großschirma it should be around 50 km.
