Pater und Nonne, Rock formation in Iserlohn, Germany.
Pater and Nonne are two limestone towers rising about 60 meters high and creating distinct vertical shapes along the Lenne River. These rock formations stand out from the forested landscape of North Rhine-Westphalia with their impressive height and rugged stone faces.
These limestone towers formed during the Middle Devonian period around 380 million years ago as part of a reef system. A cave at the base called Grürmannshöhle held bones from Ice Age animals, evidence that the site held human interest long before modern times.
The rocks take their names from local legend about a monk and nun whose story has shaped how people see and talk about this place for generations. Visitors often come here curious about this tale and the meaning it holds in regional folklore.
You can reach this spot through several hiking and mountain biking trails that wind through the surrounding forest. Visitor signs at the location and well-marked regional routes help you find your way around and plan your time outdoors.
These towers sit within a limestone band that stretches from the Bergisches Land to Balve, holding numerous cave systems throughout the region. This geological feature creates a connected landscape of karst formations that few visitors fully realize extends so widely.
