The exhibition is arranged in the western wing of the first floor of the monastery. Visitors can follow up the most characteristic minerals and fossils, as well as the geografical conditions of their formation. There is an elefant found in the Salgótarján basin, as well as prehistoric plant imprints from Ipolytarnóc.

Some botanical interrests of the region are presented by our photo exhibition. 35 plant species are possible to investigate making use of the coloured photographies in 30x40 cm measurements and the short reviews. All of them are placed onto the walls of the stairway in the monastery building.
