The Düren Biological Station has converted the old goods shed of the former Nideggen-Brück railroad station into the permanent natural history exhibition "Rur and Rock". The station building is located directly in the Rur valley with a connection to the Rur valley railroad.

In the exhibition, visitors are introduced to the inhabitants of two habitats that could not be more different. The low mountain river compared to the imposing red sandstone cliffs. In attractive and informative dioramas, the inhabitants of these habitats, such as beavers, grasshoppers, antlions and smooth snakes, are presented both visually and acoustically. A bird clock tells you when which birds in the region sing and the oak tree gives you an insight into its inner life.
Rufel, the mascot, accompanies young and old through the habitats presented and arouses curiosity for even more exciting experiences on a hike through the Rureifel.
