This unique cave offered an ideal environment for early humans providing shelter, running water, space and light. It’s not surprising then that archaeologists have discovered that people have lived here for around 70,000 years. Excavations have revealed that Devetashka Cave is one of the richest sources of Neolithic (6th millennium – 4th millennium BC) cultural artefacts in the world.
Devetashka Cave is no longer home to humans but is still used by a wide variety of animals including many that are listed as endangered. For this reason the cave is completely closed to visitors during June and July which is the breeding season for mammals in the region including some 30,000 bats that call it home.
In fact, there are thirty-four species of mammals, twelve species of protected amphibians and eighty-two species of bird found in the immediate region.
During the 1950s, when Bulgaria was part of the Soviet Eastern Bloc, the cave was used as a storage depot for petrol and food. According to some researchers, the cave later became a secret base before being decommissioned.
