Hamburg's 1241 trade alliance with Lübeck is regarded as the founding moment of the Hanseatic League, and the city still governs itself as one of Germany's three city-states. The Port of Hamburg is Europe's third-largest after Rotterdam and Antwerp, and roughly 2,500 bridges cross its canals and waterways, more than Venice and Amsterdam combined. Der Spiegel, Die Zeit and broadcaster NDR are headquartered here, anchoring one of Germany's largest media clusters. The Elbphilharmonie concert hall, built atop a former cocoa warehouse in the HafenCity docklands, opened in 2017 after a decade of cost overruns.
