In ancient times the forests and plateaus, streams and river valleys of the Soonwald-Nahe Nature Reserve were in parts more densely populated than today. Witness to this are many deserted settlements, ruins and mysterious wall remnants.
There are still many unexplored evidences of the past. The Celts left cairns and refuge towers behind, the Romans a complete network of streets to which the Ausonius street belongs and parts of villas such as the beautiful mosaic floor in Bad Kreuznach.
The spirit of the middle ages can be felt in the many castle ruins and old churches. This is true in particular about the grand monastery ruins on the Disibodenberg, where Hildegard von Bingen lived and practised. Even today a fascinating place.
