Stala‘c’tite from the ‘c’eiling, stala‘g’mite on the ‘g’round. This mnemonic can help you to identify the wonderful stone formations at the Lurgrotte, Austria’s largest dripstone cave. Here calcium mineral deposition over millions of years has yielded enchanting natural artworks both fragile and massive, with fantastic names meaning prince, giant and grand candle stick. You can explore this fascinating cavern complex accompanied by an expert guide, starting from either Peggau or Semriach.
The first person daring to enter the depths of Lurgrotte was the Italian cave scientist Max Brunello. In 1894 he discovered the Great Dome. This huge hall with an area of 120m by 80m and a height of 40m is among the biggest of its kind in central Europe and can be reached from the Semriach entrance. During guided tours a special atmosphere is created in the chamber by dramatic sound and lighting effects. Along the approximately 2km trail accessible from Semriach you can marvel, for example, at the forty-ton "giant" being probably the thickest hanging stalactite in the world.
