Rock breakthrough / tunnel from WWII. On the right side of the river, a path went up to the rock. Nice view, but be careful: there are no more railings!
On the way to the Diebsteinshoehle you should also visit the place. On a garden bench or stone you can relax well. It can be exhausting for cyclists. There are many large stones (or small cliffs) at the site
The Stone Church is a rock formation. The weathered rocks form towers, crevices and caves. An iron cross is attached to one such cave. Hence the name Stone Church.
