Despite its small size it is regarded as one of Poland's most beautiful caves and attracts numerous visitors. Its corridors lead through five chambers and caverns, that are ornamented with speleothems, such as stalactites, stalagmites and columns of calcified rock deposited over tens of thousands of years. In order to maintain an internal temperature of 8 to 10 °C (46 to 50 °F; 281 to 283 K) and 95 percent humidity required to preserve the cave's historical value and ecological integrity a maximum of fifteen people accompanied by a guide are admitted to enter the cave every fifteen minutes. In front of the entrance is an info center illuminated by optical fiber, that exhibits the cave's archeological and paleontological discoveries that include a replica of a Neanderthal camp, Mousterian assemblages and fossilized bones of contemporary Paleolithic fauna.
The cave was discovered in 1963 by Józef Kopeć and Feliks Wawrzeńczak, students of a local technical school. After extensive research and documentation by Tymoteusz Wróblewski and Zbigniew Rubinowski, geologists at the Świętokrzyskie branch of the Polish Geological Institute it was opened to the public in 1972.
The five chambers of the cave were formed during the middle Devonian era, approximately 350 million years ago. Inside, there are traces of occupancy by Neanderthal dating back 50 to 60 thousand years. Remains and fossils of Cave hyena and cave bear, that inhabited the cave and countless bones of mammalian species, such as Woolly rhinoceros and mammoths were unearthed at the site.
