This area was an important trading spot. From here goods and the valuable salt was shipped. Because the depth of the Ilmenau was not very deep, shallow boats like the ‘Salzewer’ (salt cog) were used. You can see one example lying in the Old Harbour. From here the boats went down the Ilmenau until they met the Elbe river. The goods were traded to far away regions, especially to Lübeck and from here to partners of the Hanseatic League around the Baltic Sea and other partners elsewhere. On its way, the gopds were repacked to bigger ships. Of course the boats didnt't returned empty. They were filled with different wares and you can see the Old Crane which was used for unpacking the packages from the ships.
