Zeedijk (English: "Sea dike") is a street in the old centre of Amsterdam. The street is the northern and eastern boundary of De Wallen red-light district and runs between Prins Hendrikkade and Nieuwmarkt. Historically an area riddled with crime and drug addicts, the area went through a revitalization and is now the main street of Amsterdam's Chinatown, where locals come to eat at Vietnamese, Thai and Chinese restaurants. The Zeedijk neighbourhood is also known as the Nautical Quarter (Dutch: Nautisch Kwartier) because of its past as a sailor's neighbourhood.
