For hundreds of years the salt fish trade was in the hands of German merchants of the Hanseatic League. The museum in the Symbister Pier House tells how ships from Hamburg, Bremen and Lubeck sailed to Shetland every summer, bringing seeds, cloth, iron tools, salt, spirits, luxury goods and hard currency. Generations of the same families made the voyage and some merchants are buried in the islands. The Hanseatic Booth is open all year. Visitors can pick up a key from the shop across the road (shop open hours are 9am-1pm & 2pm-6pm Monday to Saturday) or at other times the key is in the house across from the shop.
