Hamburg (German: [ˈhambʊʁk] , locally also [ˈhambʊɪ̯ç] ; Low Saxon: Hamborg [ˈhambɔːç] ),[citation needed] officially the Free and Hanseatic City of Hamburg (German: Freie und Hansestadt Hamburg; Low Saxon: Friee un Hansestadt Hamborg), is the second-largest city in Germany after Berlin, as well as the overall 8th-largest city and largest non-capital city within the European Union with a population of over 1.9 million. Hamburg's urban area has a population of around 2.5 million and is part of the Hamburg Metropolitan Region, which has a population of over 5.1 million people in total. At the southern tip of the Jutland Peninsula, Hamburg stands on the branching River Elbe at the head of a 110 km (68 mi) estuary down to the North Sea, on the mouth of the Alster and Bille. Hamburg is one of Germany's three city-states alongside Berlin and Bremen, and is surrounded by Schleswig-Holstein to the north and Lower Saxony to the south. The Port of Hamburg is Germany's largest and Europe's third-largest, after Rotterdam and Antwerp. The local dialect is a variant of Low Saxon. (Source: Wikipedia.org, CC BY-SA)
