Dungeons under Opatów, Underground medieval museum in Opatów, Poland.

The dungeons under Opatów are a museum in a guided underground route of about 500 metres, formed from former town cellars and warehouses linked beneath the market square, streets and townhouses. It runs on three levels and passes chambers such as Żmigród, Mała Lessowa, Górnicza, Strzelnica, Partyzancka, Kupcowej, Składowa Lessowa, Przechowalnia, Kupiecka and Geologiczna. Entry and exit are at the same point, at pl. Obrońców Pokoju 18.

The cellars under Opatów began to form most likely in the 13th century, and the oldest details visible along the route date from the 15th century. Members of the Kraków Cave Tourism Club, led by engineer Stanisław Nowosielski of Kraków Polytechnic, explored them in the 1960s and 1970s. From 1971 miners from PRG Bytom carried out rescue and securing work under specialists from the AGH University of Kraków, and the route opened to visitors in 1984.

The route passes through chambers with names like Żmigród, Mała Lessowa, Górnicza, Strzelnica, Partyzancka, Kupcowej, Składowa Lessowa, Przechowalnia, Kupiecka and Geologiczna. An exhibition inside covers the town and the Opatów region. The cellars began as private merchant stores and were later joined into one guided walk.

Bring warm clothing since underground temperatures stay cool year-round regardless of the season above. The guided tours let you see all areas clearly and understand how the complex is organized.
