Propas' cave with its 13000m2 and more than 113000m3 is the largest underground chamber in Serbia.
It is accessed trough 70m vertical shaft and consists of a single huge chamber full with speleotems, archaeological and paleontological remains. (Including one whole skull of cave lion and many "modern" zoological remains)
Its genesis, strange that it is, is under further study.
