The Weser is a river in Northwestern Germany. Formed at Hannoversch Münden by the confluence of the rivers Fulda and Werra, it flows through Lower Saxony, then reaching the Hanseatic-town Bremen (see: Hanseatic League), before emptying 50 kilometres (31 mi) further north at Bremerhaven into the North Sea. On the opposite (west) bank is the town of Nordenham at the foot of the Butjadingen Peninsula; thus, the mouth of the river is in Lower Saxony. The Weser has an overall length of 452 kilometres (281 mi). Together with its Werra tributary, which originates in Thuringia, its length is 744 kilometres (462 mi).
