Poland: Castle of the Teutonic Order of Malbork

The Castle of the Teutonic Order in Malbork, located in the Polish town of Malbork, is the largest castle in the world measured by land area. It was originally built by the Teutonic Knights, a German Roman Catholic religious order of crusaders, in a form of an Ordensburg fortress. The castle is a classic example of a medieval fortress and, on its completion in 1406, was the world's largest brick castle. Source: Wikipedia
