Detailed information about the museum on

Postojnska Jama

in detail

It is located inside the Passage of New Signatures, 50 m from the entrance into the Postojna Cave. Postojna Cave is the cradle of a special branch of biology – speleobiology; tens of different new animals, perfectly adapted to life in the darkness, have namely been discovered and recorded here. Although scientists for a long time believed that life without the sun or the seasons was not possible, numerous animal species that inhabit the underground world of Postojna have proven the contrary. By far the best known inhabitant of the Postojna underground world is undoubtedly the proteus (Proteus anguinus), often called the human fish, it is however not the only one at all.

Visitors get to know some of the most interesting cave animals in the Proteus Cave Vivarium, where some basic karstology and speleobiology concepts are also presented, as well as special characteristics of the subterranean habitat and the most representative cave-dwelling animals. Visitors learn about the world creation while watching a 13-minute video presentation in the Proteus Vivarium Hall.
