Gleboka Grotto

The Gleboka Grotto, located in Krucze Rocks on Mount Zborow, was discovered during the operations to extract calcite before World War II. Entry was gained by the so-called Szpatowcow Funnel, which is currently also used by tourists.

In 1942, limestone was extracted here for a short time but during the excavation the central section of the cave was discovered and unfortunately destroyed. As a result of originally having two entrances, the karst cavity was divided into two parts and acquired two additional openings at the bottom of the excavation. In the 1970’s the southern chamber of the grotto was adapted for large numbers of visitors with the construction of a massive concrete staircase. In 2006, the staircase was rebuilt and extended, which slightly altered their course. The current shape of the cave was achieved during the work carried out to adapt it for tourist traffic in 2010. As a result, the northern and southern sections were connected by a new corridor and the openings to the quarry have been permanently sealed off. The microclimate inside re-stabilized thus improving the living conditions for the underground organisms. The cave was electrically illuminated and has a total of 175m of corridors. The dripstone covering is heavily damaged as a result of the excavation of calcite which was used to the mid 20th century as a fluxing agent in the manufacture of glass. Intense karst formations can be seen in the cave, which have lead to the reconstruction of dripstones as well as numerous fissures caused by tectonic movements. Some of them have been exploited by flowing underground streams which, in the past, have led to the formation of caves on Mount Zborow. The Gleboka Grotto is the first cave in the Czestochowa Uplands that has been opened to tourists. Its advantage is the fact that it is easily accessible with a safe descent to the lower reaches of the cave. It is located within the territory of the Mount Zborow nature reserve.
