Nonne

To that end the rock crevice below the summit plateau was widened into an artificial cave, used as a guardhouse.

In addition, an artificial, earth embankment, about 35 m long, was built.

In 1888 the Nonne was climbed for the first time for fun and without using ladders.

Hitherto the rocks had always been climbed with the aid of ladders even after the watchtower had closed.

This has however resulted in erosion damage on the surrounding areas of forest and hillsides.
