Malbork, Pomerania, Poland.
Originally known as Marienburg, Malbork Castle is one of the largest surviving Gothic fortified buildings in Europe.
In the years 1309-1457 Malbork was the seat of the Grand Master of the Teutonic Knights, and the town surrounding the castle was the capital of the Teutonic Order.
