The Rheinauhafen is a 15.4 hectares urban regeneration project in Cologne, Germany, located along the river Rhine between the Südbrücke and Severinsbrücke, just south of the inner city's historic old town. The project is set around the actual Rheinauhafen, a formerly commercial harbour developed during the 1880s, and spans 2 kilometres in the north-south direction and 200 metres east-west at its widest.
