Wismar

The old city of Wismar was one of the original three sea-trading towns, along with Lübeck and Rostock, which banded together in 1259 to combat Baltic pirates. From this mutual defense pact grew the great and powerful private-trading bloc, the Hanseatic League (the Hanse in German), which dominated the Baltic for centuries. The wealth generated by the Hanseatic merchants can still be seen in Wismar's ornate architecture.
