It was discovered in 1966, near the village ofKletno inPoland. It is famous for its many excavations of thecave bear (Ursus spelaeus).[1]
The first 200 m (660 ft) of the cave was discovered in October 1966 during the mining process in the newly established quarry Kletno III. In 1967, new corridors were discovered, including the middle partsSale pałacowe ("Palace Halls"), and, in January 1972, the lowest parts were discovered. New parts of the cave were uncovered in the years 2014 to 2015. In total, the cave has a length of over 2 km (1.2 mi) and is currently the longest cave in theSudetes.[1]
