The Hanseatic City of Lübeck is the second-largest city in Schleswig-Holstein, in northern Germany, and one of the major ports of Germany. It was for several centuries the "capital" of the Hanseatic League ("Queen of the Hanse") and because of its Brick Gothic architectural heritage is on UNESCO's list of World Heritage Sites. In 2005 it had a population of 213,983. Situated at the Trave River, Lübeck is the largest German port on the Baltic Sea. The old part of the town is an island enclosed by the Trave. The Elbe-Lübeck Canal connects the Trave with the Elbe River. Another important river near the town centre is the Wakenitz. Autobahn 1 connects Lübeck with Hamburg and Denmark (Vogelfluglinie). The borough Travemünde is a sea resort and ferry port at the coast of the Baltic Sea. Its central station links Lübeck with a number of lines, notably the line to Hamburg.
