Seegrotte travel guide

Seegrotte, located in Gemeinde Hinterbrühl, boasts a fascinating and diverse history. Originally a gypsum mine in the 1800s, it gained notoriety in 1912 after a disastrous explosion flooded the lower levels with 20 million liters of water, creating what is now known as Europe's largest subterranean lake. This event transformed the mine into a unique natural wonder that attracts visitors from around the world.

During World War II, the Seegrotte was requisitioned by the German military and used as a secret aircraft factory. The Nazis produced parts for the He 162 jet fighter within its depths, adding a layer of historical intrigue to the site.

Post-war, the Seegrotte was rediscovered and eventually opened to the public in 1932 as a tourist attraction. Today, visitors can enjoy guided boat tours on the underground lake, exploring the mine’s eerie beauty and rich historical tapestry. Whether you're a history buff or a nature enthusiast, the Seegrotte offers a captivating glimpse into Austria's past.

Seegrotte is renowned for its vast subterranean lake, one of the largest underground lakes in Europe, offering a mesmerizing boat tour through its crystal-clear waters.

The temperature within the grotto remains a cool 9°C (48°F) year-round, providing a refreshing escape from the summer heat.

One of the standout features is the captivating light installations that illuminate the grotto, highlighting the natural beauty of the rock formations and creating an ethereal atmosphere.

Seegrotte, nestled in the serene area of Gemeinde Hinterbrühl, boasts the largest subterranean lake in Europe. This underground marvel was formed accidentally in 1912 after a mining blast inadvertently flooded the tunnels.

Post-war, it was meticulously restored and opened to the public in 1932. Visitors today can explore the eerie yet enchanting labyrinth of tunnels and embark on a boat ride across the crystal-clear lake.
