Considering that karstic phenomena are quite common and amplified in Oltenia mountains, in order to complement ecosystems in this province, an information area has been reserved regarding living conditions in the spelean environment and also connection means to this environment. In other words, the artificial cave referred to in the basic exhibition, through its valuable design and quality (spectacular speleothemes: spiral horn, stalagmite dome, valance etc.; the sound system playing the sound of water droplets and cries of bats, and the discrete light "washing" the speleothemes), all these conduct the visitor in the specific atmosphere of the underground space.
