The IJ-Hallen, which calls itself “the largest flea market in Europe”, is the best place for bargain hunters who love a good haggle. One weekend a month, over 750 vendors – most of whom are artisans or private sellers – cram into two giant warehouses on the post-industrial NDSM wharf. Shopping here can be a bit of a sport, as there’s a lot of stuff to wade through, from mid-century West German vases to vintage jeans and rare vinyl. But if you have the patience and a keen collector’s eye, chances are that you’ll find something fabulous here. What’s more, prices are reasonable, so you could bag a steal.
