The riverfront is certainly one of the main urban axis of Köln (Cologne). Its main tourist attraction and landmark, the cathedral, as well as the central train station, are located close to the margins of the Rhine. The city harbor area, the Rheinauhafen, built in the 1880’s, has gone through a redevelopment process over the last decade. Based on a competition design of the 1990’s, construction on the 15 hectare site started in 2002. The middle of three ‘crane houses’ won a prize for best office development in 2009. With good weather, the walkway is a busy route for pedestrians and cyclists.
