Wassermannsloch, Karst spring cave in Eisenerz, Austria

The Wassermannsloch cave extends for 1084 meters behind a permanent siphon, making it one of the longest water-filled cave systems in Austria.

In 1747, Joseph Anton Nagel conducted the first documented exploration of Wassermannsloch while serving as an envoy for the Austrian Emperor.

The name Wassermannsloch comes from a tale about a water spirit who revealed the location of iron deposits at Erzberg to local inhabitants.

The cave discharges between 50 and 10,000 liters of water per second, serving as the primary karst spring in the southwestern Hochschwab region.

The cave system contains extensive underwater passages that required specialized diving equipment for exploration, leading to detailed mapping since 1995.
