Hadamar Castle was initially Eberbach Monastery. In 1320 the monastery became the property of Count Emich of Nassau. The count turned the monastery into a moated castle with a farm, tithe barn and city wall.

A beautiful photo motif with a great view of the Lahn, but above all a bridge full of history. The stone round arches date back to the 16th century. During the Thirty Years' War, part of the bridge was blown up and replaced by the metal construction in the 19th century. As far as I know, this combination is unique and makes the bridge a cultural monument.

Medieval atmosphere when staying overnight in the youth hostel. The thick walls of the rooms and the great view of the castle opposite were a new experience. Food was good. Packed lunch available for an additional charge.

An absolute eye-catcher and the castle is being restored so we can hope for a reopening to the public.

Runkel is a great medieval photo motif: old bridge, castle and half-timbered houses...

From the eastern side of the Lahn bridge one has a picture book view of the Bug Runkel. But watch out, the old bridge is narrow - drivers and tourists taking photos sometimes get in the way here 😀
