The Altstadt (literally "old town") is one of the 49 boroughs of Düsseldorf, Germany; it belongs to central City District 1. The Düsseldorfer Altstadt is known as "the longest bar in the world" (längste Theke der Welt), because the small Old Town has more than 300 bars and discothèques; supposedly, each establishment's bar-counter connecting to one next door.
