The maar is located precisely at a SE-NW disruption in the basal complex. The Lower Devonian, structureless Ulmen tier with sand-, siltstone and clay slate is cropping out. Particularities The Jungferweiher is to the north of the Ulmen maar. It fills a shallow depression tilted toward the south. This previously silted up prior dry maar was flooded in 1942 by damming up the Nollenbach. Since then, water has been draining into the Ulmen maar and serves the Cochem-Zell district with drinking water. Since 1989 this water from the Jungferweiher has been treated, removing the phosphor from agriculture! The Jungferweiher along with the Ulmen maar is a nature conservancy known for its abundance in migratory birds!

Castles of Manderscheid

The spa town of Manderscheid is most famous for two medieval castle ruins that stand directly opposite each other on steep mountain spurs not far from the town's alleyways. The massive complexes are separated only by the little Lieser river and a meadow, which in summer becomes a perfect place for a breather while hiking the Eifelsteig trail or for a family picnic with children. On a weekend in August, however, the castles and the meadow are ideal settings for a spectacular festival with quaint crafts, jugglers, jousting tournaments and minstrel singing. In Advent, the Manderscheid Castle Christmas lends the town a special magic. The freely accessible upper castle with its five-storey keep still looks martial today. The lower castle can be explored on guided tours - even at night - or on your own; it only remains closed in bad weather.
