are six historic brick buildings on the Upper Trave River next to the Holstengate.
Built in the 16th–18th centuries, the houses stored salt that was mined near Lüneburg
and brought to Lübeck over the Stecknitz Canal. The salt was then shipped to several ports
in the Baltic region, where the commodity was relatively rare, but was in high demand
for the preservation of food. The salt trade from the late Middle Ages
onward was a major reason for the power of Lübeck and the Hanseatic League. (Source: Wikipedia)
