In 1885, a pier was developed in Karlshagen. Today it is the most important yachting port of Usedom. Between 1939 and 1945, Karlshagen lay in the restricted area of the army laboratory Peenemünde Army Research Center.
Karlshagen also was the location of the housing development for high-level personnel and scientists working in the nearby laboratory. Although the buildings were largely destroyed in the air raids of 1943/44, some parts are preserved. From 1949 to 1989, Karlshagen belonged to the German Democratic Republic. During this period, the area north of Karlshagen, including the village Peenemuende, was a restricted-access area.
The 75-metre-high pylons of a three-phase 110 kV alternating current overhead line running between Peenemuende and Karlshagen are visible for a considerable distance. This line was built in the early 1950s, in order to transport the electrical power generated on the island to the mainland, as it was no longer needed in Usedom after the laboratory was shut down. Later, a branch line was established to the transformer station in Karlshagen. After the Peenemuende power plant was shut down in 1990, the branch of the overhead line to the plant was dismantled, so now only the Karlshagen transformer station is fed by the line running across the Peene.
