Flohmarkt in der Kölner Altstadt

In the organizer's words:

At the flea market in the old town, you can browse through the many colorful stalls while enjoying the view of the Rhine. For over 40 years, people have been dawdling and selling here in a beautiful setting. There is a wide range of antiques, books, records, jewelry, furniture and much more!

If you would like to stand on the other side of the stalls, you can simply register. The flea market is divided into two sections for sellers.
Section A is between Hohenzollernbrücke and Machabäerstraße and costs 15 euros per meter. Section E is located between Machabäerstraße and the Bastei and costs 10 euros per meter. Tickets can be booked via the booking hotline 0221-235365 or by email at info@coelln-konzept.de.
