Appingedam (; Gronings: "n Daam") is a city and former municipality in the northeastern Netherlands. Although there is no certainty as to the exact age of Appingedam, historical research demonstrates that the place in which the city would eventually be built had been inhabited for over a millennium. Specifically, the area in which the earliest traces of human settlements have been reported is the Wierde, a quarter located in the northern part of the city centre. Today, a narrow, winding street by the same name runs along the waterfront as a living testimony to the times gone by. The characteristic landmarks of the old Wierde are still recognisable today: the historical East-West Canal, called “Diep,” dug to the south of the Wierde, diked on both sides, still defines the unique layout of the downtown Appingedam.
