Rügen
Rügen is Germany's largest island. It is located off the Pomeranian coast in the Baltic Sea and belongs to the state of Mecklenburg-Vorpommern.
The "gateway" to Rügen island is the Hanseatic city of Stralsund, where it is linked to the mainland by road and railway via the Rügen Bridge and Causeway, two routes crossing the two-kilometre-wide Strelasund, a sound of the Baltic Sea.
Rügen has a maximum length of , a maximum width of in the south and an area of. The coast is characterised by numerous sandy beaches, lagoons and open bays, as well as peninsulas and headlands. In June 2011, UNESCO awarded the status of a World Heritage Site to the Jasmund National Park, characterised by vast stands of beeches and chalk cliffs like King's Chair, the main landmark of Rügen island.
The island of Rügen is part of the district of Vorpommern-Rügen, with its county seat in Stralsund.
The towns on Rügen are: Bergen, Sassnitz, Putbus and Garz. In addition, there are the Baltic seaside resorts of Binz, Baabe, Göhren, Sellin and Thiessow.
Rügen is very popular as a tourist destination because of its resort architecture, the diverse landscape and its long, sandy beaches.
Geology
The chalk cliffs of the Jasmund peninsula belong to the Rügen Chalk unit and were formed during the Maastrichtian stage of the Late Cretaceous, around 70 million years ago.Geography
The main body of the island, known as Muttland, is surrounded by several peninsulas. To the north lie the peninsulas of Wittow and Jasmund, connected to each other by the Schaabe sandbar and to Muttland by the Schmale Heide, an embankment at Lietzow and the Wittow Ferry. The northern peninsulas are separated from Muttland by several lagoons or bodden, the largest of which are the Großer Jasmunder Bodden and Kleiner Jasmunder Bodden. Major peninsulas in the south are Zudar and Mönchgut which both face the Bay of Greifswald. Strelasund separates the island from the southern mainland.File:Königsstuhl und Viktoria-Sicht.jpg|thumb|left|Jasmund National Park, with its chalk cliffs, the symbol of Rügen: Victoria-Sicht and Königsstuhl from the Baltic Sea
Rügen has a total area of, or if the adjacent small islands are included. The maximum diameter is from north to south, and from east to west. Of an overall coastline, are sandy Baltic Sea beaches, and sandy bodden beaches. The highest elevations are on the Jasmund peninsula: Piekberg and Königsstuhl.
The northern part of the Bay of Greifswald, the Rügischer Bodden, is a large bay in the south of Rügen island, with the island of Vilm lying just offshore. At the western end of the bay, the peninsula of Zudar runs out to the southernmost point of Rügen, at the eastern end the highly indented peninsula of Mönchgut projects into the sea. This peninsula ends in the east at the cape of Nordperd near Göhren and in the south at the cape of Südperd by Thiessow. In the west of the peninsula of Mönchgut a narrow, bar, the Reddevitz Höft, separates the two bays of Having and Hagensche Wiek.
In the north-east of the island of Rügen is formed by the peninsula of Jasmund, which is joined to the heart of the island, Muttland, by the bar of Schmale Heide between Binz-Prora and Sassnitz-Mukran and by a rail and road embankment at Lietzow. The Schmale Heide separates the outer bay of Prorer Wiek from the lagoon of the Kleiner Jasmunder Bodden. On the peninsula of Jasmund are the Piekberg, the highest point on Rügen, and the Königsstuhl, a chalk cliff in Stubbenkammer, which forms the most striking landmark on the island. Another bar, the Schaabe, links Jasmund to the peninsula of Wittow in the north of Rügen. The Schaabe, in turn, separates the outer bay of Tromper Wiek from the lagoon of the Großer Jasmunder Bodden. The peninsula of Wittow and the long, narrow peninsula of Bug to the west are separated from the main body of Rügen by the Rassower Strom, the Breetzer Bodden and the Breeger Bodden. The Wittow peninsula is adjoined in the north by Cape Arkona. Just under a kilometre to the northwest, located at 54°41' N, is the northernmost point of Mecklenburg-Vorpommern. Below this cliff on the shoreline is the Siebenschneidersteinthe fourth largest glacial erratic boulder on Rügen.

The northwestern and western sides of Rügen are also highly indented, but a little flatter. Offshore are the larger islands of Hiddensee and Ummanz as well as the smaller islands Öhe Liebitz and Heuwiese. Sand removal and deposition by the Baltic Sea has to be constantly countered by dredging operations to the north and south of Hiddensee, otherwise Hiddensee would merge with Rügen within a few years. Rügen is dotted with many glacial erratic boulders, of which the 22 largest belong to legally-protected geotopes.
Land use
The heartland of Rügen is gently rolling, and the area is characterised primarily by agriculture. East of the town of Bergen auf Rügen the land climbs to and to in the southeastern hill country of the Granitz. The soil on Rügen is very fertile and productive, particularly in Wittow, the breadbasket of the island. There are major cabbage-producing regions.Two German national parks are situated on Rügen: the Western Pomerania Lagoon Area National Park, in the west, and the Jasmund National Park, a smaller park including the chalk cliffs. There is also a nature reserve, the Southeast Rügen Biosphere Reserve, consisting of the peninsulas in the southeast.
Climate
The climate is in the temperate zone. According to the Köppen climate classification the northern parts of the island and the coastal regions are under the influence of the oceanic climate, meanwhile the remaining majority of the area is dominated by the humid continental climate. The winters are not particularly cold, with mean temperatures in January and February of ; and summers are mild and temperate, with a mean temperature in August of. There is an average rainfall of and approximately 1800–1870 hours of sunshine annually.Administration
Administratively, Rügen is part of the district Vorpommern-Rügen. Its subdivisions are the Amt Bergen auf Rügen, West-Rügen, Nord-Rügen and Mönchgut-Granitz and the Amt-free municipalities of Binz, Putbus and Sassnitz. Overall, there are 45 municipalities on Rügen, four of which have town status.History
Pre-history and the Germani
Discoveries in the bodden indicate that there has been settlement here since the Stone Age. All over Rügen are numerous stone monuments, such as megalithic tombs and altar stones that have survived to the present day. By the 1st century, the inhabitants of Rügen were part of the East Germanic tribe of Rugii, who occupied roughly the region that was later to become Western Pomerania and who gave the island its name. The Rugii may have originated from Scandinavia or evolved from autochthonous tribes. In the Migration Period, many Rugii moved south and founded an empire in Pannonia.Slavic Rani
From the 7th century, the West Slavic Rani built an empire on Rügen and the neighbouring coast between Recknitz and Ryck. It decidedly affected the history of the Baltic Sea area and the surrounding Obodritic and Liutician occupied mainland for the next few centuries. Many traces of their life can be found today.File:Slavnost svatovitova na rujane.jpg|left|thumb|The Celebration of Svetovid on Rügen, Alphonse Mucha, The Slav Epic
The basis of their military strength was a combination of the Ranian navy and a favourable location. Denmark, which was at that time very successful in Great Britain and Scandinavia, was neither able to match its Ranian rivals in the Baltic Sea region nor protect its coastline from Ranian armies until well into the 12th century. Meanwhile, the Ranians built numerous castles and temples in the Barth-Jasmund-Gristow triangle.
The temple hill of Jaromarsburg, at the northern tip of Rügen and dedicated to the god Svetovid, was significant well beyond the boundaries of the Ranian empire. After the fall of Radgosc it became the chief shrine for the pagan northwestern Slavs. The administrative centre of the empire was Charenza, possibly on the site of the present-day hillfort known as Garz or Venz. The main trading centre of the empire was Ralswiek at the southernmost point of the Großer Jasmunder Bodden.
Principality under Danish suzerainty
In 1168, the Danish king, Valdemar I, and his army commander and advisor, Bishop Absalon of Roskilde destroyed the Svetovid temple in the hillfort at Cape Arkona, ending both the territorial and religious autonomy of the Rani; their former monarchs became Danish princes of Rügen. The Rani prince Jaromar I was a vassal of the Danish king and Christianized the island's inhabitants. In 1184, the Pomeranians, whose rule had previously extended as far as the land of Gützkow and to Demmin and thus made them the immediate neighbours of the now Danish Principality of Rugia, were commissioned by their overlord, the Holy Roman Emperor, to seize Rügen for the empire, but were defeated in the Bay of Greifswald.Under Danish rule the Principality of Rugia changed its character. Danish monasteries were established. German colonists were introduced into the land and soon they became the largest and most culturally influential group within the population. The Slavic cultural element disappeared, mostly due to the lack of their own Slavic church structures, so that the Rani were absorbed in the period that followed into the now German-influenced people of Rügen. In addition to the colonization of the country and the building of new monasteries and churches, towns were also re-established. In 1234, the Rügen Prince Wizlaw I founded the town of Stralsund and granted Greifswald market rights in 1241. The power of the towns grew rapidly, forcing Rügen's rulers to make concessions—for example, the prince's castle at Barth was slighted and Schadegast, the princely "twin" of the municipally-controlled Stralsund, was ousted in favour of the latter.
In 1304 a storm surge, known as the All Saints' Flood, devastated the island and flooded the peninsula between Mönchgut and Ruden.
