Darlowo Port (Port code: PLDAR), is located in Darlowo, a seaside town in the West Pomeranian Region, at the south coast of the Baltic Sea, north-western Poland. In 1878 the town gained a railway connection to Danzig (Gdańsk) and Stettin (Szczecin); it simultaneously became a popular health resort, mainly due to the exceptional climate. Between 1871 and 1945, Rügenwalde (Darłowo) was part of Germany and was the site of a highly guarded military base. It was here that the largest artillery piece in the world, Schwerer Gustav, was constructed and tested by the Nazis during World War II.
