The discovery of the Atta cave
The Atta cave was discovered by accident: Quarrymen of the Biggetal lime works couldn't believe their eyes on 19 July 1907. As the enormous dust cloud of the explosion subsided, they found themselves looking into a rock crevice which had been exposed and was flooded with sunshine. The quarrymen of Attendorn had – without knowing it – exposed the entrance to one of the greatest natural wonders of the world: the entrance to the fabulous Atta cave. Named after the Princess Atta, who gave her name to the Hanseatic city of Attendorn. More about the cave
