Trödel - und Antikmarkt Aachener Platz

In the organizer's words:

Düsseldorf's cult flea market and, incidentally, one of the oldest and most beautiful markets in Germany. Here you can expect 400-500 stalls every Saturday and a correspondingly diverse range: private jumble sales, antiques (tent hall), a weekly market for fruit and vegetables and gastronomy, for example the popular Café Sperrmüll. Sometimes there's also live music. Doesn't that mean anything to you? Then now we know what you'll be doing next Saturday.
