The City Hall square stone

Second interesting item located on the square of the City Hall (Rådhuspladsen), a sculpted granite stone that indicate the "entry point to the city" (actually the city a long time ago). It also served as a "kilometer zero" indicator, defining the distance from Copenhagen to major cities. You can also see the insignia of the city (with three towers, the sun and the moon).

There are others of those cornerstones, located at other "doors" of the city.
