Ok, let me try:
Bremen and Lübeck still retain a distinctive Hanseatic air. In Bremen you would want to see the Rathaus with its impressive upper hall. Lübeck is full of old warehouses and merchant's houses from the era. have a look at the Holstentor and the historic churches. For a more academic approach, visit the Hamburg City history Museum
www.hamburgmuseum.de . Hope this is of some help.
