Swing Bridge in the Rheinauhafen
Cologne's oldest crossing over Rhine water: a listed swing bridge from 1896 that pivots aside using hydraulics powered from the Malakoff Tower.
On the left bank of the Rhine between the Malakoff Tower and the Chocolate Museum, the listed swing bridge rotates its structure to the side, allowing boats to enter the Rheinauhafen.

- Type
- Listed swing bridge (steel truss girder)
- Location
- Altstadt-Süd, Innenstadt district, on the left bank of the Rhine
- Opened
- 5 August 1896
- Spans
- 28.334 m (long arm), 18.30 m (short arm)
- Width
- 10 m, of which 5 m carriageway
- Clearance height
- 8.20 m above Cologne gauge
To balance the unequal weight of its two arms, the shorter arm was paved with heavy stone and the longer arm with lighter wood – a clever engineering solution ensuring the bridge stays balanced when rotating.
History
The bridge opened on 5 August 1896 alongside the expansion of the Rhine side channel into a harbour and is considered Cologne's oldest crossing over Rhine water. In 1986/87 the industrial monument underwent a full overhaul. It is now assigned to the Chocolate Museum Foundation, which it also provides with a direct access route.
Engineering and Construction
The rotation mechanism is controlled electro-hydraulically at a pressure of 5 MPa, generated inside the Malakoff Tower of 1850. This pressure was originally supplied by a power plant built for the harbour expansion between 1892 and 1898. Every rotation is preceded by a lift of 11.2 cm. Because the two arms differ in weight, the short arm was surfaced with stone and the long arm with wood.
Today
The structure is painted in the traditional Cologne bridge green. Anyone wishing to enter the Rheinauhafen — now used predominantly by leisure and yacht boats — must contact the harbourmaster; between 8 am and 8 pm the bridge is opened on request.
Did You Know
As early as 1984, repairs to the hydraulics cost close to one million Deutschmarks. A restoration of this cultural monument is planned for 2026 under the Kulturinvest programme, with federal funding of around 3.3 million euros set to preserve one of the few remaining structures of this kind still standing in Germany.
