Malbork is noted for its Gothic castle, Malbork Castle, one of the most striking in Europe.

Founded in the 13th century by the Teutonic Knights, the town is noted for its Gothic Marienburg Castle, one of the most striking in Europe. Formerly the mighty residence of the Grand Master of the Teutonic Knights, whose power was crushed at the biggest single military engagement in Mediaeval Europe, the Battle of Grunwald (1410).

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

Malbork was founded by the monks - knights, members of the Order of St Mary's Hospital of the German House in Jerusalem (this is the full name of the Teutonic Knights). In the 13th- 15th centuries at the right high bend of the Nogat, they built a three-part fortress and a town. The settlement was given the Chelmno town charter which quickened the development of the town. In the 15th century, within the town there were 174 houses, 85 of which were situated along the street market which can still be seen on the plan of the Old Town. The castle was placed on the UNESCO List of the World Culture Heritage in 1997, which proves its high value. On Mondays and on some festive days Malbork Castle Museum is closed. There is possibility to visit only castle's areas and some interiors.
