The Ryck is a river in Mecklenburg-Vorpommern, Germany. From its source near Bartmannshagen, part of the Süderholz community northeast of Grimmen, the Ryck flows for about 28 kilometres (17 mi) to the east, reaching Greifswald shortly before its mouth. The larger part of the river outside Greifswald is also referred to as Ryckgraben. In Greifswald, the Ryck provided both the medieval Hanseatic port and natural salt evaporation ponds, as due to the low elevation, hypersaline water of the Baltic Sea is driven into the river by the wind, flooding the lower meadows on the Ryck's northern bank. In the High Middle Ages, the Ryck marked the southern border of the Principality of Rügen and the northern border of the County of Gützkow. West of Greifswald, the Ryck fed the Boltenhägener Teich, a medieval lake. The old Hanseatic port in Greifswald is now an open-air ship museum.

The Wendelstein 7-X (abbreviated W7-X) reactor is an experimental stellarator built in Greifswald, Germany, by the Max Planck Institute for Plasma Physics (IPP), and completed in October 2015. Its purpose is to advance stellarator technology: though this experimental reactor will not produce electricity, it is used to evaluate the main components of a future fusion power plant; it was developed based on the predecessor Wendelstein 7-AS experimental reactor. As of 2023, the Wendelstein 7-X reactor is the world's largest stellarator device. After two successful operation phases ending in October 2018, the reactor was taken offline for upgrades. The upgrade completed in 2022. New fusion experiments in February 2023 demonstrated longer confinement and increased power. The goal of this phase is to gradually increase power and duration for up to 30 minutes of continuous plasma discharge, thus demonstrating an essential feature of a future fusion power plant: continuous operation.The name of the project, referring to the mountain Wendelstein in Bavaria, was decided at the end of the 1950s, referencing the preceding project from Princeton University under the name Project Matterhorn.The research facility is an independent partner project of the Max-Planck Institute for Plasma Physics with the University of Greifswald.

Greifswald University Library (German: Universitätsbibliothek Greifswald) is the official library of the University of Greifswald, situated in Greifswald, Germany. Its earliest days go back to the founding of the university in the year 1456, and it became Germany's first centralised university library in the year 1604.

The central university library is completed by various specialised libraries of the university's departments.

Greifswald Medical School (German: Medizinische Fakultät der Universität Greifswald) is a division of the University of Greifswald, Germany, consisting of the university's medical school and the adjacent Greifswald University Hospital. Its roots date back to the founding of the university in the year 1456, and it is therefore one of the oldest such institutions in Europe.

Greifswald University Hospital (German: Universitätsmedizin Greifswald) in Greifswald, Germany is a teaching hospital for the University of Greifswald's medical school. Greifswald University Hospital is owned and operated by a non-profit Anstalt des öffentlichen Rechts in cooperation with the university and serves as one of the primary hospitals in the state of Mecklenburg-Vorpommern. It also fills the function of a tertiary referral hospital for the health care region.

Ziese is a river of Mecklenburg-Vorpommern, Germany. It forms a pseudobifurcation: its water west of Rappenhagen flows into the Dänische Wiek near Greifswald, and its water east of Rappenhagen flows into the Peenestrom near Wolgast.

Weitenhagen is a municipality in the Vorpommern-Greifswald district, in Mecklenburg-Western Pomerania, Germany. The former municipality Diedrichshagen was merged into Weitenhagen in May 2019.

Greifswald Süd (German: Bahnhof Greifswald Süd) is a railway station in the town of Greifswald, Mecklenburg-Vorpommern, Germany. The station lies of the Angermünde–Stralsund railway and the train services are operated by DB Regio Nordost and Ostdeutsche Eisenbahn.

The University of Greifswald Faculty of Law and Economics (German: Rechts- und Staatswissenschaftliche Fakultät der Ernst-Moritz-Arndt-Universität Greifswald) is one of five faculties of the university that is situated in Greifswald, Germany.

Swedish Pomerania (Swedish: Svenska Pommern; German: Schwedisch-Pommern) was a dominion under the Swedish Crown from 1630 to 1815 on what is now the Baltic coast of Germany and Poland. Following the Polish War and the Thirty Years' War, Sweden held extensive control over the lands on the southern Baltic coast, including Pomerania and parts of Livonia and Prussia (dominium maris baltici). Sweden, which had been present in Pomerania with a garrison at Stralsund since 1628, gained effective control of the Duchy of Pomerania with the Treaty of Stettin in 1630. At the Peace of Westphalia in 1648 and the Treaty of Stettin in 1653, Sweden received Western Pomerania (German Vorpommern), with the islands of Rügen, Usedom, and Wolin, and a strip of Farther Pomerania (Hinterpommern). The peace treaties were negotiated while the Swedish queen Christina was a minor, and the Swedish Empire was governed by members of the high aristocracy. As a consequence, Pomerania was not annexed to Sweden like the French war gains, which would have meant abolition of serfdom, since the Pomeranian peasant laws of 1616 was practised there in its most severe form. Instead, it remained part of the Holy Roman Empire, making the Swedish rulers Reichsfürsten (imperial princes) and leaving the nobility in full charge of the rural areas and its inhabitants. While the Swedish Pomeranian nobles were subjected to reduction when the late 17th-century kings regained political power, the provisions of the peace of Westphalia continued to prevent the pursuit of the uniformity policy in Pomerania until the Holy Roman Empire was dissolved in 1806. In 1679, Sweden lost most of its Pomeranian possessions east of the Oder river in the Treaty of Saint-Germain-en-Laye, and in 1720, Sweden lost its possessions south of the Peene and east of the Peenestrom rivers in the Treaty of Stockholm. These areas were ceded to Brandenburg-Prussia and were integrated into Brandenburgian Pomerania. Also in 1720, Sweden regained the remainder of its dominion in the Treaty of Frederiksborg, which had been lost to Denmark in 1715. In 1814, as a result of the Napoleonic Wars, Swedish Pomerania was ceded to Denmark in exchange for Norway in the Treaty of Kiel, and in 1815, as a result of the Congress of Vienna, transferred to Prussia.

Greifswald (German pronunciation: [ˈɡʁaɪfsvalt] ), officially the University and Hanseatic City of Greifswald (German: Universitäts- und Hansestadt Greifswald, Low German: Griepswoold, Kashubian: Grifiô) is the fourth-largest city in the German state of Mecklenburg-Western Pomerania after Rostock, Schwerin and Neubrandenburg. In 2021 it surpassed Stralsund for the first time, and became the largest city in the Pomeranian part of the state. It sits on the River Ryck, at its mouth into the Danish Wiek (Dänische Wiek), a sub-bay of the Bay of Greifswald (Greifswalder Bodden), which is itself a sub-bay of the Bay of Pomerania (Pommersche Bucht) of the Baltic Sea. It is the seat of the district of Western Pomerania-Greifswald, and is located roughly in the middle between the two largest Pomeranian islands of Rugia (Rügen) and Usedom. The closest larger cities are Stralsund, Rostock, Szczecin and Schwerin. It lies west of the River Zarow, the historical cultural and linguistic boundary between West (west of the river) and Central Pomerania (east of the river). The city derives its name from the dukes of Pomerania, the House of Griffin (Greifenherzöge), and thus ultimately from the Pomeranian Griffin (Pommerscher Greif), and its name hence translates as "Griffin's Forest". The University of Greifswald, which was founded in 1456, is the second-oldest university in the Baltic Region after the University of Rostock. The city is well-known for the ruins of Eldena Abbey (formerly Hilda Abbey), a frequent subject of Caspar David Friedrich's paintings, who was born in the city when it was part of Swedish Pomerania. Greifswald is the seat of the Pomeranian State Museum (Pommersches Landesmuseum). The recently built Ryck Barrier (Rycksperrwerk) protects the city from exceptionally high tides and storm surges moving up from the Baltic. The city's population was listed at 59,332 in 2021, including many of the 12,500 students and 5,000 employees of the University of Greifswald. Greifswald draws international attention due to the university, its surrounding BioCon Valley, the Nord Stream 1 gas pipeline which ends at nearby Lubmin, and the Wendelstein 7-X nuclear fusion projects.
