The city of Hamburg is situated at three rivers, the Alster, the Bille and the Elbe, at 53°33′ N 10°0′ E.
Hamburg's proximity to the main trade routes of the North and Baltic Seas quickly made it a major port of Northern Europe, and its alliance (1241) with Lübeck on the Baltic is considered the origin of the powerful Hanseatic League of trading cities.
Hamburg was one of the major centers of the heavy metal music world in the 1980's.
