The City Municipality of Bremen is the capital of the German federal state Free Hanseatic City of Bremen (also called just “Bremen” for short), a two-city-state consisting of the cities of Bremen and Bremerhaven. With around 570,000 inhabitants, the Hanseatic city is the 11th largest city of Germany as well as the second largest city in Northern Germany after Hamburg. Bremen is the largest city on the River Weser, the longest river flowing entirely in Germany, lying some 60 km (37 mi) upstream from its mouth into the North Sea, and is surrounded by the state of Lower Saxony. The flag of Bremen (used by both the city of Bremen and the state Free Hanseatic City of Bremen) consists of at least eight equal horizontal stripes of red alternating with white, and checked at the hoist. It is colloquially known as Speckflagge (bacon flag). Full HD.
