The Eisenstein Cave is a show cave in the municipality of Bad Fischau-Brunn ( Lower Austria ). The cave was discovered by chance in 1855, as there was a quarry above the then closed entrance . In the course of the dismantling work, the entrance was exposed. The owner of the quarry, Imperial Knight Eissner von und zu Eisenstein , had the work stopped after the discovery became known, the cave bears his name today. Franz Mühlhofer explored the cave in 1896 at the age of 15 with a group of his own age.

The length of the cave known today is 2341 meters, the maximum depth −73 meters, the entrance is 380 meters above sea level. The so-called shaft cave is located in the limestone mountains of the northern limestone Alps ( Triaskalk and dolomite ) in an area with local conglomerate rock deposits , exactly on the so-called thermal line . There is a thermal spring in the cave, the water temperature of which is given as between 13 and 16.5 degrees Celsius. The Eisenstein Cave is located on an NNE-SWW trending fissure zone (fault) with an average of 47 ° dipping zone directly at the break of the eastern edge of the Alps against the Vienna Basin and has up to 5 overlapping passages; their maximum horizontal extension is 147 m.

The cave can be divided into 3 sections:

  • Main course (entrances - source, viewing section)
  • Market halls (southern part)
  • New part (north part)

The cave is poor in stalactites , but a specialty is the so-called pearl sinter , a lime deposit in the form of round spheres , which has arisen in the cavities due to the special cave climate .

The entrance to the cave can be reached on foot or by car from the Vienna Basin (junction at Bad Fischau or Brunn an der Schneebergbahn ). Guided tours of the cave have been taking place since 1907. The cave is looked after by the Alpine Club section “Allzeit True”, which also provides the cave guides. Guided tours take place on weekends from May to October. An artificial entrance tunnel was built to make the cave more accessible. The originally exposed entrance to the cave is about 50 meters northeast of the artificial entrance. In the cave, a climbing system was built from the entrance to the thermal spring, some with iron ladders in the vertical sections.
