Ochrona przyrody nieożywionej na terenie Wielkopolskiego Parku Narodowego

The collection of 20 erratics complements the exhibition of diverse forms of biotic and abiotic nature of the Wielkopolski National Park. Within the rocks there are examples of magmatic, sedimentary and metamorphic ones. The most interesting are indicator erratics, derived in known Scandinavian mother regions and transported onto Polish Lowland around 18,8 ka BP. The petrographic garden plays didactic and geotourist role and stays for a favourite weekend direction.
