Wertheim was a large department store chain in pre-World War II Germany. It was founded by Georg Wertheim and operated various stores in Berlin, one in Rostock, one in Stralsund, and one in Breslau. Its Jewish owners were forced out after 1933 by the new Nazi government. After the war, owner Karstadt operated various store branches across Germany under the Wertheim name, all of which either closed or were rebranded Karstadt.

Stralsund, officially the Hanseatic City of Stralsund, is the fifth-largest city in the northeastern German federal state of Mecklenburg-Western Pomerania after Rostock, Schwerin, Neubrandenburg and Greifswald, and the second-largest city in the Pomeranian part of the state. It is located on the southern coast of the Strelasund, a sound of the Baltic Sea separating the island of Rügen from the Pomeranian mainland.
