The fascination of the Obir stalactite caves comes from the incomparable mix of nature and man, from the symbiosis of 200 million years of history and modern technology. The caves were discovered in 1870 when miners set out in search of lead and zinc. Today we are fascinated by a wonder. A subterranean world that reveals itself to us for a moment: Carefully placed light illuminates the absolute darkness. Music breaks the boundless silence. The stalactites are alive - proud and unapproachable, ambassadors of a distant world.
