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.
