Langenau Castle

Langenau Castle is a stronghold at the confluence of the Gelbach and Lahn rivers near Obernhof, featuring a square Romanesque tower and Gothic defensive walls. The complex includes flanking towers and a substantial timber-framed building from the 17th century connected to the medieval structures through preserved passages.

The castle was first recorded in 1243 when Countess Mechthild of Sayn left it to the Archbishopric of Cologne. The archbishopric later granted it to the Langenau noble family, from whom the stronghold took its name.

The castle displays the transformation from a fortress to a residential stronghold through its mix of Gothic walls and Romanesque tower. Visitors can observe this architectural evolution while moving through the different sections.

Access to the grounds is straightforward as the stronghold sits near the river and is easily visible from the area. The pathways between different buildings are in good condition, allowing visitors to explore the complex independently.

In 1851, Countess Giech transformed the entire complex into a hospital and residence for children from low-income families. This repurposing preserved the buildings while giving them a purpose far removed from their original defensive role.
