The capital of North Rhine-Westphalia, Dusseldorf got its start centuries ago on the Rhine River's east bank, but today the regional economic powerhouse straddles both banks. Altstadt is not just Dusseldorf's lovely old town but also where the city's nightlife is based and where Altbier, its native dark beer, is plentiful. Königsallee, Dusseldorf's famous shopping street, (just Kö to locals) has many high end stores. The Museum Kunst Palast has one of the Rhineland's best art collections.
