The Brunnenhöhle (also called Mainonihöhle , cadastral number 1911/8) is a 131 meter long conglomerate cave at the bottom of a well shaft in Gainfarn, a district of the Lower Austrian town of Bad Vöslau . The cave was first described by Adolph von Morlot in 1847 , in 1980 only 60 meters of passage length had been explored. The cave is not freely accessible.

location

With a total length of 131 meters, the Brunnenhöhle is one of the most important caves in the Vienna Woods . According to the Trimmelsch mountain group structure , the cave is in the subgroup 1911 Hoher Lindkogel , in Gainfarn near Bad Vöslau. The upper entrance of the well shaft is located on the property on Hauptstrasse No. 8 in Gainfarn at 280 meters above sea level.

Well shaft

In the 20 meters deep, the top 5 meters bricked, well shaft with a diameter of almost 1.5 meters there is an old, heavily rusted ladder that leads down to just above the water level. From there you can get off on iron trusses. The shaft is closed at the top with a concrete cover. The water depth was sounded on March 2, 1985 at two meters.

Subsequent courses

From the traverses you slip through a narrow passage into a very low room with a loamy floor. There is a larger, shallow pool of water to the east. To the north-east there is a 20-meter-long, rising chasm with an average height of two meters. At the end of it, a silt branches off to the right , which leads back to the southwest. This part of the cave, which is only 0.3 meters high, was only explored in the 1980s. At its end there is also a pool of water that is only two meters away from the one in the entrance area. A connection between these two parts cannot therefore be ruled out. At the end of the chasm, another corridor leads to the left, which is wider and higher than the previous one, to the northeast, past col-like extensions. At its end, room heights of up to three meters are reached.

geology

The cave is located in the Miocene Age Vöslauer conglomerate .

In the uppermost section, the shaft leads through clayey soils until it reaches the conglomerate at a depth of 16 meters. Damaged sintered jewelry as well as small, clumsy eccentric formations can be seen in the colossal shapes of the cave ceiling . In the sandy sediments of the soil there are isolated fragments of sintered blankets and sintered blankets. According to old descriptions, however, the cave is said to have had beautiful stalactite jewelry in the past.
