Hiddensee () is a car-free island in the Baltic Sea, located west of Germany's largest island, Rügen, on the German coast. The island has about 1,000 inhabitants. It was a holiday destination for East German tourists during German Democratic Republic (GDR) times, and continues to attract tourists today. It is the location of the University of Greifswald's ornithological station. Gerhart Hauptmann and Walter Felsenstein are buried there. Name The name Hedinsey surfaces as early as the Prose Edda and the Gesta Danorum written by Saxo Grammaticus and means "Island of Hedin". The legendary Norwegian king, Hedin, was supposed to have fought here for a woman or even just for gold. Under Danish rule the name Hedins-Oe ("Hedin's Island") was common. Even in 1880 the island was shown in German maps as Hiddensjö and, in 1929, in German holiday guides as Hiddensöe. Its full Germanization to Hiddensee is thus relatively recent. Geography Hiddensee is about long, about wide at its narrowest point and about wide at its broadest point. It is the largest island within the Western Pomerania Lagoon Area National Park and belongs to the district of Vorpommern-Rügen in the state of Mecklenburg-Western Pomerania. It lies west of the island of Rügen and is divided into an undulating, over northern part (Dornbusch, whose highest point is the Bakenberg at ), a dune and heath landscape in the central area (Dünenheide) and a flat, only few-metres-high southern part, the Gellen. In the northeast are the two spits of Alter Bessin and Neuer Bessin. The island is bounded by the Schaproder Bodden and Vitter Bodden to the east, the Gellenstrom (the shipping channel to Stralsund) to the south and the open Baltic Sea to the west and north. Geology The island of Hiddensee is, from a geological perspective, a very young landscape and was formed during the last ice age about 12,000 years ago. The ice age left behind here a Young Drift landscape. As a result of thawing inland ice, the underlying land rose and the hollows filled with water; the predecessor of what became the Baltic Sea, Ancylus Lake emerged. As a result, only protruding ridges like the Dornbusch remained visible, as islands. The overall shape of the coast in the southern area of the Baltic Sea was formed during the Littorina Transgression about 7,000 to 2,500 years ago. Around 5,000 years ago, the sea level attained its present level
