It is located about 45 kilometres (28 miles) east of Lübeck and 30 kilometres (19 miles) north of Schwerin, and is part of the Hamburg Metropolitan Region. Its natural harbour, located in the Bay of Wismar, is well-protected by a promontory. The population was 42,219 in 2013. It is the capital of the district of Nordwestmecklenburg. A unique representative of the Hanseatic League city type, with its Brick Gothic constructions and many patrician gable houses, Wismar has been included in the UNESCO list of World Heritage Sites since 2002, together with the historical core of Stralsund.
