It is situated north of the Szczecin Lagoon (Polish: Zalew Szczeciński; German: Stettiner Haff) estuary of the River Oder. About 80% of the island belongs to the German district of Vorpommern-Greifswald in the state of Mecklenburg-Vorpommern. The eastern part and the largest city on the island, Świnoujście (German: Swinemünde), are part of the Polish West Pomeranian Voivodeship. The island's total area is 445 square kilometres (172 square miles) (the German part 373 square kilometres (144 square miles); the Polish part 72 square kilometres (28 square miles). Its population is 76,500 (German part 31,500; Polish part 45,000).
With an annual average of 1906 sunshine hours, Usedom is the sunniest region of both Germany and Poland, and it is also one of the sunniest islands in the Baltic Sea, hence its nickname "Sun Island" (German: Sonneninsel, Polish: Wyspa Słońca).
The island has been a tourist destination since the Gründerzeit in the 19th century, and features resort architecture. Seaside resorts include Zinnowitz and the Amber Spas in the west, the Kaiserbad and Świnoujście in the east.
The island is separated from the neighbouring island of Wolin to the east by the Strait of Świna (German: Swine), which is the main route connecting Szczecin Bay with the Pomeranian Bay, a part of the Baltic Sea. The strait between the island and the mainland is called the Peenestrom; it is a downstream extension of the valley of the Peene river, which flows into the westernmost part of the Stettin Lagoon. The island is mostly flat, partly covered by marshes.
Geographical features include a number of lakes:
|Lake Name||Elevation||Surface Area|
|Cämmerer See||0.3 m (0.98 ft)||0.18 km2 (0.069 sq mi)|
|Gothensee||0 m (0 ft)||5.56 km2 (2.15 sq mi)|
|Kachliner See||0 m (0 ft)||1.00 km2 (0.39 sq mi)|
|Schmollensee||0 m (0 ft)||5.03 km2 (1.94 sq mi)|
|Wolgastsee||−0.6 m (−2.0 ft)||0.47 km2 (0.18 sq mi)|
The largest town on the island is Świnoujście (Swinemünde), which has a population of 41,500. Another town, Usedom, gives its name to the island. The largest town in the German part is Heringsdorf (from 2005 to 2006 called Dreikaiserbäder, literally "Three Emperor Spas").
There are many seaside resorts on the Baltic Sea coast, including Zinnowitz and Koserow in the west – and the three Imperial Spas Ahlbeck, Heringsdorf, and Bansin forming a town, as well as neighbouring Świnoujście in the east of Usedom.
The hinterland is called Achterland, referring to the Achterwasser lagoon (Rear Waters). It is characterized by unspoilt forests, lagoon landscapes, and hills, as well as calm villages such as Loddin and Balmer See with its golf course.
Settled since the Stone Age, the area was probably inhabited by Germanic Rugians, before the Polabian Slavs moved in during the fifth, sixth, and seventh centuries. Around the island, Wendish/Scandinavian trade centres such as Vineta/Jomsborg and Menzlin were established. In 1128 the Slavic Pomeranian Duke Wartislaw I was converted to Christianity through the efforts of Otto of Bamberg. In 1155 the Premonstratensians established a monastery in Grobe, generally known as Usedom Abbey, which in 1309 was moved to the village of Pudagla. In the meantime, a Cistercian nunnery was founded in Krummin and soon almost the whole island was in the possession of one or the other of the ecclesiastical orders. During the Reformation, ownership passed to the Slavic dukes of Pomerania, who took over the island.
During the Thirty Years' War, on June 26, 1630, the Swedish Army under King Gustavus Adolphus landed in the village of Peenemünde, located on the Peenestrom strait. Usedom was annexed by Sweden after the war for almost a century, until in 1720 it was sold for 2 million thalers to Prussian King Frederick William I. In 1740 Frederick the Great of Prussia developed a seaport in Swinemünde.
The small village of Peenemünde came to prominence again during World War II. The Luftwaffe tested missiles and rockets, including the V-1 and V-2 nearby. Germany used thousands of slave laborers on Usedom during World War II.
In 1945 the eastern part of the island, together with the city and port of Swinemünde (now Świnoujście), was assigned to Poland under border changes promulgated at the Potsdam Conference, and the surviving German inhabitants of the town were expelled to the west. The territory was repopulated with Poles, most of whom had been expelled by the Soviets from what had been eastern Poland.
The Isle of Usedom is one of Germany's major holiday and recreation areas due to its beaches, its natural environment, and seaside towns such as Zinnowitz and Heringsdorf, which have been frequented by the German and international nobility as well as the general public. St. Peter Church in Benz is featured in the works of several artists, including the German-American painter Lyonel Feininger who spent summer vacations on the island from 1909 to 1921. Hotels and bed and breakfast establishments are available on both sides of the German-Polish border. In addition to the coastline, the hinterland features nature reserves, castles, lakes and historic villages. Points of interest include:
- Usedom Botanical Gardens, Mellenthin, a botanical garden
- Karnin Lift Bridge, a technical monument to the former bridge over the Peenestrom.
- Dannenfeldt Mausoleum
