P1 Trödelmarkt

In the location's words:

With up to 1000 traders, the "P1" market in Düsseldorf is one of the largest markets anywhere. It is even listed in a guide to the 100 most beautiful markets in Europe, alongside the world-famous markets in Paris and London. High-quality second-hand fashion, furniture, silver, watches or jewelry are available in abundance. Real junk characterizes the picture. New goods are limited to selected offers that fit into the framework of the events.
