1. Malbork Castle
Number one in our list of largest castles is the Malbork Castle that is located in a village in Northern Poland. It’s a beautiful place and was built by the Teutonic Knights, a religious order founded back in 1190. Later what we today know as the village of Malbork grew around the place and the castle itself became a part of the Royal Russia. During the WWII the castle suffered severe damages and had to be renovated. Today the castle serves as a museum and holds exhibitions.
