Rinnende Mauer, Natural monument and spring in Molln, Austria.
Rinnende Mauer is a water spring in the Steyrschlucht gorge where water flows continuously over limestone walls, creating distinctive wet patterns on the rock surface. The formation sits within a protected nature reserve that preserves this unusual geological feature.
This limestone spring formed over thousands of years as mineral-rich water continuously flowed down the rock face, gradually building up the distinctive tufa deposits. The geological process that created this formation remains active today.
The site forms part of the European Natura 2000 network, representing significant natural heritage that requires protection for future generations.
The visitor center in Molln provides information about the gorge and helps with route planning before you set out. The path can be slippery during wet weather, so sturdy shoes and caution are recommended.
Visitors often notice that the water never stops flowing, even during dry summer months. The spring taps into deep underground sources that remain stable throughout the year.
