2 Best Sights in Düsseldorf, The Rhineland

The Kö-Bogen II office complex bills itself as having Europe's largest green façade, with eight kilometers of green hedges and approximately 30,000 plants in total.

Just outside Düsseldorf, the Düssel River forms a valley, called the Neanderthal, where the bones of a Stone Age relative of modern man were found. The impressive museum, built at the site of the discovery in the suburb of Mettmann, includes models of the original discovery, replicas of cave drawings, and life-size models of Neanderthal Man. A new highlight, the Höhlenblick tower, affords a view onto the spot where Neanderthal bones were found.
