Stralsund, officially the Hanseatic City of Stralsund, is a city in the Pomeranian part of Mecklenburg-Vorpommern, Germany. It is located at the southern coast of the Strelasund, a sound of the Baltic Sea separating the island of Rügen from the mainland.
The Strelasund Crossing with its two bridges and several ferry services connects Stralsund with Rügen. The Western Pomeranian city has been the capital of the Vorpommern-Rügen district since the 2011 district reforms. It is the fourth-largest city of Mecklenburg-Vorpommern and, together with Greifswald, Stralsund forms an Oberzentrum, one of four high-level urban centres of the region.
Stralsund was granted city rights in 1234 and was one of the most prosperous members of the medieval Hanseatic League. In 1628, during the Thirty Years' War, the city came under Swedish rule and remained so until the upheavals of the Napoleonic Wars. From 1815 to 1945, Stralsund was part of Prussia. Since 2002, Stralsund's old town with its rich heritage is honored as a UNESCO World Heritage Site, along with Wismar in Mecklenburg.
