The document discusses two historical mining sites in Tarnowskie Gory, Poland: the Black Trout Adit and the Historical Mine of Silver, Lead, and Zinc Ores. The Black Trout Adit was once the longest mining adit in the region at 15 km long. It is now a popular tourist attraction accessible by boat. The Historical Mine of Silver, Lead, and Zinc Ores is a 150-km network of underground passages that gives visitors a glimpse into the difficult work of past miners and remnants of machinery from when it was operational.

2. Tarnowskie Gory, in the northern part of the Upper Silesian Industrial Area, used to be famous for its lead and silver ores. In the 16 th century it was the largest mining centre in Silesia. As the area was rich in the ore deposits, the mining industry developed till 1912. At the end of the 19 th century, its 15-km-long adit was the longest in the area. Though no longer in operation, the Black Trout Adit is one of major tourist attractions in Silesia. The 600-metre-long part of an old mine, open to tourists since 1957, is only accessible by boats. The passage in the dark corridors of the drain adit, accompanied by colourful stories told by the guide, is an unforgettable experience! Black Trout Adit

3. Another site worth visiting is the Historical Mine of Silver, Lead and Zinc Ores is a unique monument of ore mines in Europe. It is an underground labyrinth of 150-km-long underground mining passageways, drifts and corridors. The Historical Mine of Silver, Lead and Zinc Ores is a precious relict of the rich mining traditions in the region of Tarnowskie Gory. Here one can learn about the hard work of the ore miners (called "gwarki") and see the partly flooded post-mine machines and drifts going along the 1700-metre-long tourist route, part of which is covered by boat. Going down in the pit-cage of the Aniol (Angel) shaft is also an exciting adventure. Having visited the mine, one can enjoy a visit to the steam-driven machines in the open-air museum situated close to the Historical Mine of Silver, Lead and Zinc Ores. Definitely worth seeing!
