In 1894 this cave became world famous when 7 cavers were trapped underground for a week by a flash flood. This book tells the story of the rescue with excerpts and photos from old news papers, diaries etc. The history of exploration, geology and hydrology, flora and fauna etc are all covered in this detailed monograph. Trevor Shaw describes some early cave "Stamps" sold to raise funds for exploration work. Nicely produced on art paper SB (Deutsch - German)

The Lurgrotte cave is Austria's largest and most beautiful stalagtite cave. It is a through cave and an active river cave. The water of the Lurbach enters the cave near Semriach at 640 m asl and leaves at an resurgence near Peggau at 400 m asl. The cave system in between is 6 km long. On both sides of the cave is a show cave. The description on this page is mainly for the Semriach part.

Near Semriach a huge entrance leads into the cave, which beacme famous in 1894. Seven cave explorers were trapped inside the cave by high water. The Imperial Engineering Battalion was sent to free them. The European public held their breath for nine days and the papers only reported about the Lurgrotte cave. This event boosted the development of the cave, as it was well known from now on.

The Semriach part of the Lurgrotte shows an active river cave, as the Lurbach enters the cave at the portal. But soon it vanishes and the cave shows numerous speleothems, which are apparently named with phantastic names. The most impressive point of the tour is the Großer Dom (Big Dome) which is the biggest chamber of the cave, 120 m long, 80 m wide and 40 m high. It is said to be one of the biggest chambers of Central Europe.

A summer highlight is the multivision show in the big dome. Sound and vision fills the huge chamber. In winter this show is not possible, as it would disturb hibernating bats.

The winter highlight are Erlebnisführungen (adventure tours) which are made with carbide lamps on old parts of the show cave. This paths are less good developed, but still easy to visit. This part of the cave was originally developed as a show cave, but the paths were partly destroyed by floods and so it is not part of the regular tour any more.
