Rock sundial in Schwellhäusl
Stone sundial at Schwellhäusl - Bavarian Forest National Park In collaboration with Dr. Paul Kestel from Zwieselerwaldhaus and Michael Haug of the National Park administration, the world's unique sundial was created. With sunshine, there is not only the day time, the glass ball behind is also brought to light.
But this only happens twice a year when the sun shines - in spring and autumn for day and night are equal, the sun is at noon exactly in the sky that the jets hit through the borehole in the rock just the glass ball.
"The sundial shows the beautiful hours only."
