SOS Info Centre Proteus

Visit the SOS Proteus Information Centre for the protection of olms in the tunnels under the old town of Kranj. Learn first-hand from the researchers of the Tular Cave Laboratory about the life of the olm in their inaccessible, underground world, why they are endangered and why underground waters should remain clean. By visiting, you become a supporter of the endangered olm, as the funds raised from admission fees go entirely towards the research and protection of this endangered species.

The SOS Proteus Info Centre is something for curious visitors. It is equipped with information boards, video presentations and aquariums with olms. The main purpose of the centre is to educate and raise awareness about the importance of preserving the olm and the groundwater resources from which 99% of Slovenia’s drinking water comes.

Groundwater, where the olm lives, is a precious source of drinking water!

The centre displays rescued olms that were brought to the surface by groundwater floods, where they would not have survived. So, after 200 years, showing olms to the public no longer has a negative impact on nature and is animal-friendly. This is the concern of the researchers at the Tular Cave Laboratory, where they have been studying and protecting olms for 60 years. At the same time, the SOS Proteus Info Centre is the first of its kind in the world to monitor the impact of visitors on olms. By visiting, you not only become a direct supporter of the olms, but you also contribute to improving their living conditions.
