Haus Ley

Haus Ley is a medieval water castle positioned on raised ground along the Agger River between Engelskirchen and Runderoth. The two-story stone structure uses the river as a natural defensive barrier, displaying the characteristic design of noble fortifications from that era.

The castle was first recorded in 1370 by an abbot from Siegburg and served the County of Mark as a defensive post against the Cologne Archbishopric's power. It represents a period when regional nobles had to defend their lands against growing ecclesiastical authority.

The structure shows how medieval nobles used fortifications to control territory and trade routes in the region. You can still sense how such buildings shaped daily life and power relationships in the surrounding area.

The castle remains private property with no public access to the interior, though visitors can view and photograph the exterior from designated spots. The best views are available from the riverbank and nearby walking paths.

The name Haus Ley comes from slate rock, the geological material that defines the location where the castle was built. This detail shows how medieval builders carefully adapted their structures to the natural conditions of the landscape.
