Königsallee
The Königsallee (, literally "King's Avenue") is an urban boulevard in Düsseldorf, state capital of North Rhine-Westphalia, Germany. The Königsallee is noted for both the landscaped canal that runs along its center, as well as for the fashion showrooms and luxury retail stores located along its sides.
Nicknamed Kö by the locals, the Königsallee is by far Germany's busiest, upscale shopping street.
