The Drachenfels cliff is one of the most popular recreation spots in the “Siebengebirge” stretch on the Rhine. But the cliff’s rocks have become brittle and now work is under way to try to keep it from breaking apart.Atop the Drachenfels cliff, high above the River Rhine, sit the striking ruins of a castle. “But that could only be determined little by little.”One reason is that the cliff has dense vegetation.
