The Atta-Höhle was discovered by chance. What a coincidence! Quarrymen of the Biggetal lime works could not believe their eyes on July 19, 1907 during blasting: when the giant dust cloud of the explosion had settled, they looked into an exposed rock crevice flooded with sunny daylight. They crawled inside and what they saw left them speechless. The workers looked into a labyrinth of the most beautiful stalactite formations - artfully grown stalagmites and stalactites - stone curtains, which hung artfully from the rock ceiling, as if a decorator had made his master examination with it. The quarrymen of Attendorn had - without knowing it - uncovered the entrance to one of the greatest natural wonders of this earth: the entrance to the legendary Atta-Höhle. Named after the princess Atta, who gave her name to the Hanseatic city of Attendorn.
