A super great place that you should see

The Steinerne Stadl is a natural rock bridge that originates from a collapsed cave. This is also called a passage cave. Remains of stone tools and ceramics have been found inside the Steinerne Stadel and it is now assumed that this cave also served as a cult room from the Neolithic period to the Iron Age (and possibly later). Its proximity to the Hoffmannshöhle indicates a resonance/connection. In front of the cave you can find a free-standing stone with two deep, artificially created stone bowls. The position and arrangement of the bowls (at the top, in a free-standing stone, so very impractical for grinding grain - without protection from rainwater ...) and their shape give rise to mystical speculations about their use.

The Eisenstein Cave, whose entrances are located at 380 m above sea level, is the most important thermal cave on the western edge of the southern Vienna Basin (Fischau Mountains). The 73 m deep and around 2 km long, shaft-like cave is located on a fracture zone parallel to the slope (thermal line) in young tertiary breccia (sausage marble). The thermal spring at the deepest point of the cave has a temperature of around 15.5 °C. Collapsed blocks and corrosion forms characterize the fissures richly decorated with coral and popcorn sinter.

The place is well hidden behind the Tran Austria Gasnetze compression station Only a small plaque in the middle of a field points to the natural monument.

impressive wall in the quarry, lots of good information boards

Whenever I'm here or see the pictures, the place touches me.

Driven many times, but never discovered a source

a nice landmark, but I've never found anything resembling a source
