Description

A catastrophy in a gypsum mine created Europes biggest subterranean lake. In a routine blast in 1912 twenty million litres of water flooded the mine, so it had to be shut down.

When G. Plankenbichler had a well drilled in 1848, he found gypsum close to the surface. He decided to mine the mineral and throughout the following decades, miners dug the ground. Gypsum was subsequently used as a fertiliser.

The mine was closed in 1912. In 1932 cave explorers discovered a fantastic natural monument which had developed in the abandoned mine. Soon workers started to build safe paths to the subterranean lake and install electric light. Finally, boat excursions into the former mine became a tourist attraction.

By the end of World War II, water was pumped out of the grotto and the cave was used as an underground factory by the Nazis. 2,000 people, many of them forced labourers, had to build parts for the Heinkel HE 162 aircraft, the first jet fighter of the world. The Red Army destroyed the factory at the end of the war. After the war it took some years to restore the mine and reopen it to the public.

On the tour you see rooms that once served the miners as a chapel, common room and wine cellar, where they used to celebrate. There are even stables for working horses which had to spend all their life in the dark. The lake - which gave the mine its name Seegrotte - is situated at a depth of 60 meters below ground. A romantic boat ride takes you into a quiet and magic world. This place is very popular, 250,000 people are visiting the Seegrotte every year.

But on Whitmonday 2004 this romantic boat ride became a dead trap for four tourist from Germany and one from Belgium. The trimaran, they were sitting in, had a technical problem, one of the three hulls became leaky and the boat capsized. Most of the passengers got wet but were not harmed, but four of the tourists were trapped under the boat by the balustrade of the trimaran and drowned. The attraction was temporarily closed until 02-JUL-2004. The site is now open again, but the boat trip on the underground lake is canceled for an indefinite time. The examination of the accident is not completed until now.
