Malbork 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 Teutonic Knights, the town is noted for its Gothic Malbork Castle.

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 in Polish as Malborg or Malbork) 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 their pay. This separated the castle from the city in political terms, as the citizens resisted take-over by Poland,.

Under continuous construction for nearly 230 years, the castle complex is actually three castles nested in one another. A classic example of a medieval fortress, it is the world’s largest brick castle and one of the most impressive of its kind in Europe. The castle was in the process of being restored when World War II broke out. During the war, the castle was over 50% destroyed. Restoration has been ongoing since the war. However, the main cathedral in the castle, fully restored just prior to the war and destroyed during the war, remains in its ruined state. The castle and its museum are listed as UNESCO's World Heritage Sites.


The Castle in Malbork is the largest castle in the world by area. It was built in Prussia 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 Gothic castle. UNESCO designated the "Castle of the Teutonic Order in Malbork" and its Museum as the World Heritage Site in December 1997.[3] It is one of two World Heritage Sites in the region with origins in the Teutonic Order. The other is the "Medieval Town of Toruñ", founded in 1231 as the site of the castle Thorn (Toruñ).

Malbork Castle was founded by the Teutonic Order after the conquest of Old Prussia. Its main purpose was to strengthen their own control of the area following the Order's 1274 suppression of the Great Prussian Uprising of the Baltic tribes. No contemporary documents survive relating to its construction, so instead the castle's phases have been worked out through the study of architecture and the Order's administrative records and later histories. The work lasted until around 1300, under the auspices of Commander Heinrich von Wilnowe. The castle is located on the southeastern bank of the river Nogat. It was named Marienburg after Mary, patron saint of the religious Order. The Order had been created in Acre (present-day Israel). When this last stronghold of the western Crusades fell to Muslim Arabs, the Order moved its headquarters to Venice before arriving in Poland.

Malbork became more important in the aftermath of the Teutonic Knights' conquest of Gdañsk (Danzig) and Pomerania in 1308. The Order's administrative centre was moved to Malbork from Elbl¹g (Elbing). The Grand Master of the Teutonic Knights, Siegfried von Feuchtwangen, who arrived in Malbork from Venice, undertook the next phase of the fortress' construction.[4] In 1309, in the wake of the papal persecution of the Knights Templar and the Teutonic takeover of Danzig, Feuchtwangen relocated his headquarters to the Prussian part of the Order's monastic state. He chose the site of Marienburg conveniently located on the Nogat in the Vistula Delta. As with most cities of the time, the new centre was dependent on water for transportation.

The castle was expanded several times to house the growing number of Knights. Soon, it became the largest fortified Gothic building in Europe, on an nearly 52-acre site. The castle has several subdivisions and numerous layers of defensive walls. It consists of three separate castles - the High, Middle and Lower Castles, separated by multiple dry moats and towers. The castle once housed approximately 3,000 "brothers in arms". The outermost castle walls enclose 52 acres (21 ha), four times the acreage of the enclosed space of Windsor Castle. The developed part of the property designated as a World Heritage Site is 18.0380 ha.
