Amsterdam’s wealth began in its port with the merchants who bought and sold everything from tulip bulbs to spices from the East Indies. A little of that mercantile past can still be seen at the city’s many markets. The most famous is the Albert Cuyp food market in the Pijp neighborhood, which sells, as the city website puts it, everything from cheese to bicycle chains, six days a week. The prettiest is the Noordermarkt, a sort of grower’s market that sets up each Saturday outside the historic Noorderkerk church, next to the Prinsengracht canal. The best flea market is at Waterloo Square every day except Sunday close to the Amstel River.
