The Hanseatic City of Lübeck is the largest German port on the Baltic Sea and the second-largest city in Schleswig-Holstein, situated at the mouth of the river Trave. The city has been an important port since the 12th century. Lübeck and nearby Hamburg founded what became the powerful Hanseatic League of ports and trading towns. History also has a sweeter side for Lübeck - it is globally known for the finest marzipan.
The old town of Lübeck, although considerably damaged during the Second World War, has survived from medieval times in a pretty much unchanged or truthfully rebuilt form. It is now listed as a UNESCO World Heritage site.
Lübeck is perhaps Germany's finest example of "brick Gothic" architecture, which uses the locally available brick (as opposed to "proper" stone, which was not available to medieval builders in northern Germany) to produce quite stunning buildings.
