Malbork Castle, Poland
Poland’s pride and joy when it comes to castles is certainly this sprawling red-brick fortress. Built in Prussia by the Teutonic Knights in 1406, it was christened Marienburg (after Mary). Much of Poland had the misfortune of being destroyed in the world wars, so Poland doesn’t have much in the way of ancient castles, not the way that Spain or France or Italy does. But it does have Malbork–which, when measured in surface area, is the reigning king of castles–it is the largest castle in the world! Recognised by UNESCO, this brick masterpiece (brick castles being common in this part of Europe, see Trakai, Torun, and Turaida for further examples) is the largest brick structure in Europe. Now that’s certainly something to be proud of!
