Kwidzyn [ˈkfʲid͡zɨn] (German: Marienwerder, Prussian: Kwēdina) is a town in northern Poland on the Liwa river, with 40,008 inhabitants (2004). It has been a part of the Pomeranian Voivodeship since 1999, and was previously in the Elbląg Voivodeship (1975–1998). It is the capital of Kwidzyn County.
Geograhical location 
The Teutonic Knights founded an Ordensburg castle in 1232 and a town the following year. In 1243 the Bishopric of Pomesania received both the town and the castle of Marienwerder (German for "Mary's ait") from the Teutonic Order as fiefs, and the settlement became the seat of the Bishops of Pomesania within Prussia. The town was populated with Masurian settlers. Werner von Orseln, who died in Marienburg (Malbork) in 1330, was buried in the cathedral of Marienwerder. St. Dorothea of Montau lived in Marienwerder from 1391 until her death in 1394; pilgrims would later come to pray in the town at her shrine. The rebellious Prussian Confederation was founded in Marienwerder on March 14, 1440. In 1466, the town became a Polish fief together with the remainder of the monastic state of the Teutonic Knights after their defeat in the Thirteen Years' War.
Marienwerder became part of the Duchy of Prussia, a fief of Poland, upon its creation in 1525. The duchy was inherited by the House of Hohenzollern in 1618 and was elevated to the Kingdom of Prussia in 1701. The town became the capital of the District of Marienwerder. When after the First Partition of Poland, resulting in the re-unification of Prussia, the new Prussian Province of West Prussia was founded, Marienwerder was taken out of the Province of East Prussia and integrated into West Prussia of which it became the administrative seat. The town and district were included within the government region of Marienwerder after the Napoleonic Wars.
In 1885 Marienwerder had 8,079 mostly Lutheran inhabitants, many of whose trades were connected with the manufacturing of sugar, vinegar, and machines. Other trades were brewing, dairy farming, and fruit-growing. According to official statistics, ca. 1910 35.7% of the county's population was Polish.
After World War I, when the Treaty of Versailles became effective in January 1920 and the Polish Corridor was installed on German territory, most of West Prussia was incorporated into the Polish Second Republic. The treaty permitted the East Prussian plebiscite in a few areas. To determine if Marienwerder would remain in Germany as part of East Prussia or join Poland; 93,73% of the inhabitants of the town voted on 11 July 1920 for East Prussia, to which the town was joined.
In 1945 during World War II, Marienwerder was plundered by the Soviet Red Army. Red Army established war hospital in the town for 20,000 people. The town's old center was burned by Soviet soldiers. The post-war Potsdam Conference placed it under Polish administration in 1945. Since then it remains as part of Poland. Burned parts of the town's old center were dismantled to provide material for the rebuilding of Warsaw after its destruction in the Warsaw Uprising.

The castle 
Kwidzyn contains the partially ruined 14th century Brick Gothic Ordensburg castle of the Teutonic Order, namely the Bishops of Pomesania within the Order. Connected to the castle to the east is a large cathedral (built 1343-1384) containing the tombs of the bishops as well those of three Grand Masters of the Teutonic Knights.
The literally outstanding feature of the castle is a sewer tower which is connected to it by a bridge. The tower used to be placed at the river which has changed its course since, leaving it on dry land.
Modern town 
Other sights include the appellate court for Kwidzyn County, a new town hall, and government buildings.
A branch of the company International Paper is located in Kwidzyn, as is the Kwidzyn School of Management. The second biggest employer is Jabil which is one of world leading EMS (Electronics manufacturing services) companies. The city has a lower than national average crime and unemployment rates when compared to the average rate in Poland average. Success in this field was gained through high level of sport programs for youths. Programs such as MMTS Kwidzyn (handball) or MTS Basket Kwidzyn are the best examples of this.
