The cave bear (Ursus spelaeus) is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word cave and the scientific name spelaeus are used because fossils of this species were mostly found in caves.
The name of the cave is due to the numerous fossils of "cave bears" (Ursus spelaeus) found here. The cave used to be a home for these animals 15,000 years ago. The cave remained closed until 17 September 1975, when the underground void was artificially opened by dynamiting the entrance during the limestone (marble) quarrying works.
