On the Kachelberg near Königheim there is a listed "open-air cross" which ends here at the summit cross. Details on the Way of the Cross with all stations: de.wikipedia.org/wiki/Kreuzweg_(K%C3%B6nigheim)
Here are further ramparts and ditches of the former Wettenburg - a section of fortification on the mountain ridge that was built in the Neolithic period.
