Altstadt or “Old Town” is the historical center of Düsseldorf. Supposedly there are more than 300 bars and clubs in the small, square area so it has also gained the nickname “the longest bar in the world”. During the day it is totally like every other “old town” but at night, the younger set like to come here to party and drink. My friends and I came here at night and bar hopped. It’s a bit on the young side but it was super fun for us due to Karneval celebrations.
