Chain Bridge (Nuremberg)

The Chain Bridge (German: Kettensteg) is a pedestrian chain bridge in Nuremberg, Germany. The bridge crosses the river Pegnitz just a few meters upriver of Fronveste and Schlayerturm, fortifications in the course of the medieval city wall guarding the river's exit from the town. It connects Maxplatz in Sebalder Altstadt (the old quarter north of the river) with Untere Kreuzgasse in Lorenz, the quarter on the south side of the river.

The Chain Bridge was built in 1824 and is thus the oldest surviving chain bridge on the European continent. It was not given any specific name, but the public used to call it by what it appeared to be: a narrow pedestrian bridge (German: Steg) with chains (German: Ketten).

The bridge has two spans of 33 m each and a total length of 68 m. On either side, there are two strands of wrought iron eyebars, originally supported by three wooden towers standing on the banks of the river and on the small island, and anchored in solid masonry blocks on either side. The wooden deck was suspended from the chains by hangers, also of wrought iron.

The wooden towers were damaged by the very high floods of 1909 and, thereafter, replaced by towers of iron trusses still in existence.

As in most early suspension bridges, its bridge deck was not stiff and easily developed swaying motions under the steps of the pedestrians—and some youths enjoyed provoking the swaying on purpose.
