Deep Friedrichstollen
The Friedrichstollen deep is a former mining tunnel for drainage in the area of the Upper Silesian town of Tarnowskie Góry ( Tarnowitz ). It was created as part of the Friedrichsgrube , which was built in 1784 . The Friedrichsgrube was a lead ore and silver ore mine, the lead ores of which were smelted in the Friedrichshütte . The water exiting through a mouth hole feeds the Drama River , which has its source nearby. The tunnel is 4568 meters long and has 25 light shafts.
history
The Friedrichstollen was laid out from April 21, 1821 to 1834 and was put into operation on November 15, 1834. Before the drainage tunnel was used, eight steam engines were used to hold water in the pit. The steam engines were set up around 1790 and came from England. The mouth hole in the classical style was made of sandstone. The Friedrichstollen was used for mining purposes until 1904, after which it was initially without use.
When Upper Silesia was divided in 1922, the German-Polish border ran over the tunnel and the mouth was on the German side. In order to regulate the maintenance and future use of the tunnel and the mouth hole, an international contract was signed in Berlin.
A 600-meter-long section of the tunnel has been used for tourism purposes since 1957 under the name Sztolnia "Czarnego Pstrąga" (Black Trout Tunnels) and is part of the Route of Technical Monuments in the Silesian Voivodeship . The tunnel is used by boats between two light shafts ("Ewa" and "Sylwester").
