The Seegrotte show mine in Hinterbrühl is a disused gypsum mine with mythical-looking tunnels, a mine or barbara museum and the largest underground lake in Europe.

The Seegrotte is a former gypsum mine in the Lower Austrian market town of Hinterbrühl, about 15 km south of Vienna, which today - as from 1932 - serves as a show mine. Seven springs feed the largest underground lake in Europe, covering 6200 m². He has no natural drain.

Definitely go in if you are in the area.
The staff is great. Admission is 18 Euros and definitely worth it.
The boat trip is, of course, the absolute highlight.
