Lübeck is probably the greatest historical city in northern Germany. Located in the northernmost state of Schleswig-Holstein, this port city was part of the Hanseatic League, which dominated trade in northern Europe for centuries. It continues to be Germany's principal port on the Baltic Sea. The city is known for its distinctive brick Gothic architectural style, and its old city has been designated as a UNESCO World Heritage site.
