Stralsund is a Hanseatic town on Germany’s Baltic coast. Its Old Town has many red-brick Gothic landmarks, like the 13th-century Town Hall. The Stralsund Museum maintains a medieval merchant’s house and monastery. The Ozeaneum aquarium has tanks recreating the habitats of the Baltic Sea and North Sea, plus a penguin pool. In the harbor is Gorch Fock I, a 1933 tall ship. A bridge links Stralsund to Rügen island.
