Amsterdam’s best-known and biggest flea market sprawls in a ramshackle fashion around Waterlooplein. Two canals were filled in 1882 to form a market square that by 1893 lay at the heart of the Jewish Quarter. Before World War II this was a daily market central to Jewish life, but as Amsterdam’s Jews were deported it fell into disrepair. During the 1960s the market was reborn when dazed hippies floated in from all over Europe in the haze of their summers of love to sell bongs, water pipes, and doubtless lots of dope. Today the market has around 300 stalls flogging anything from knock-off DVDs to piles of vintage clothes, plastic jewelry, and (ironically) Nazi pilot leather jackets. If you take time to scrabble deeply around the stalls, you may even find some decent second-hand books.
