The tour covers the excavations of two historical structures - the Queen Louise Mine and the Main Key Hereditary Adit - connecting Zabrze and Chorzów, which used to be excavated almost exclusively with the use of human muscles for 64 years. The adit is 14 km long and is the longest in Europe. It is the Europe's only underground tourist route presenting the development of mining technology from the late 18th century to the present day.
Going deep down is an amazing mining time travel. The adit houses a structure that is absolutely unique in the scale of the entire European mining industry - a gallery entirely drilled in the coal bed, an underground transhipment port and the Poland's largest underground mining machinery park.
Another attraction available in the adit is an over one kilometre long underground waterway.
