Lainzer Tiergarten

The largest underground lake in Europe, one of the tourist attractions in Austria, known as the kingdom of underground fairy tales. It is located in the village of Hunterbucht, west of Vienna, with an area of 6,200 square meters. From entering the underground lake, you have to pass a tunnel about 450 meters long with a height of more than one person. Today's underground lake was a gypsum mine in the early years. On the left at the end of the tunnel is a hall with a capacity of 3,000 people formed after the plaster was mined. It was the auditorium and bar of the miners. Candles are lit on both sides of the auditorium on New Year's Day, and workers spend the festival here. In order to maintain the old appearance, there are still bright candles here. The small hall of Barbara is where the workers pray, and there is a statue of Barbara. Entering the underground lake is like walking into a labyrinth, and you can't tell the difference between east, west and northwest.
