The buzzing neighbourhood of Medienhafen constitutes a comprehensive overview of contemporary architecture. Celebrities such as Frank O. Gehry (the group of buildings at Neuer Zollhof 1-3), Steven Holl and David Chipperfield have all contributed to its metamorphosis. From the top of the 172m-high Rhine Tower (Rheinturm), you can take in the superb view of the area and the city.
