The Castle of the Teutonic Order in Malbork (Polish: zamek w Malborku; German: Ordensburg Marienburg) is the largest castle in the world by surface area. It was built in Marienburg, Prussia (now Malbork) by the Teutonic Knights, a German Roman Catholic religious order of crusaders, in a form of an Ordensburg fortress. The Order named it Marienburg (Mary's Castle). The town which grew around it was also named Marienburg.
The castle is a classic example of a medieval fortress and, on its completion in 1406, was the world's largest brick castle.UNESCO designated the "Castle of the Teutonic Order in Malbork" and the Malbork Castle Museum a World Heritage Site in December 1997. It is one of two World Heritage Sites in the region with origins in the Teutonic Order. The other is the "Medieval Town of Toruń", founded in 1231 as the site of the castle Thorn.
Malbork Castle is also one of Poland's official national Historic Monuments (Pomnik historii), as designated September 16, 1994. Its listing is maintained by the National Heritage Board of Poland.
Malbork [ˈmalbɔrk] (German: Marienburg ( listen); Latin: Civitas Beatae Virginis) is a town in northern Poland in the Żuławy region (Vistula delta), with 38,478 inhabitants (2006). Situated in the Pomeranian Voivodeship since 1999, it was previously assigned to Elbląg Voivodeship (1975–1998). It is the capital of Malbork County.
Founded in the 13th century by the Knights of the Teutonic Order, the town is noted for its medieval Malbork Castle, built in the 13th Century as the Order's headquarters in what later became known as West Prussia.
The town was built in Prussia around the fortress Ordensburg Marienburg which was founded in 1274 on the east bank of the river Nogat by the Teutonic Knights. Both the castle and the town (named Marienburg in German and Malborg or Malbork in Polish) were named for their patron saint, the Virgin Mary. This fortified castle became the seat of the Teutonic Order and Europe's largest Gothic fortress. During the Thirteen Years' War, the castle of Marienburg was pawned by the Teutonic Order to their imperial soldiers from Bohemia. They sold the castle in 1457 to King Casimir IV of Poland in lieu of indemnities.
