If you would like to learn more about tuff, you can find out more about this rock and its possible uses here in the "Weiberner Schaufenster" on the left. The path up to the right also takes you in just a few minutes to the open-air exhibition at the stone saw house, where, among other things, a stone saw and a crane clearly illustrate the work processes involved in the tuff stone. The tourist information offers regular guided tours to the impressive Weiberner tuff quarries and - like the local stone cutters' association - organizes hands-on stone hammering courses, in which individual works of art are created from volcanic rock.
The Afelskreuz (Ablasskreuz) stands on an old Roman military road. For centuries pilgrims have been pilgrimage from Bonn-Cologne to the grave of the Apostle Matthias in Trier.
