In the beginning of the 1950s, serious explorations of the cave were held, concerning its transformation into a warehouse. The studies showed that the Devetashka cave used to be inhabited (with some interruptions) during almost every historical era. The earliest traces of human presence date back to the middle of the Early Stone Age before about 70,000 years BC. The Devetashka cave is among the cave deposits with the richest cultural artifacts from the Neolithic (6th millennium - 4t h millennium BC).
The entrance of the cave is 35 meters wide and 30 meters high. About 40 meters after the entrance, the cave widens, forming a spacious hall with an area of 2,400 square meters. The height of the hall is 60 meters; at some places it reaches 100 meters.
