Zeedijk is a street standing on a dyke, and it still bends the way the dyke bent. The dyke went up in the thirteenth century to hold back the IJ, then an open arm of the Zuiderzee. It worked, and the town grew on the dried ground behind it. At number 1 stands In 't Aepjen, built around 1550, one of only two houses in Amsterdam that still show a timber front to the street.
By the seventeenth century the merchants had moved to the new canals, leaving the street to sailors and drink. Chinese seamen settled at the eastern end from 1911, and their descendants made this Amsterdam's Chinatown: shop signs run in two alphabets and the He Hua temple sits behind a Chinese palace roof. In the late 1970s heroin dealing took the street over so completely that police stayed out, and twenty years of local buying and reletting got it back. Before noon it is a quiet lane of grocers and small kitchens; at eleven at night the crowds from the red light lanes spill into it.
