This is a video from the Malbork Castle. It was built by knights of the Teutonic Order in the late 13th century. They withdrew here after the crusades in the Holy Land.
Over the next 200 years, until the late 15th century, the castle expanded several times. It is even today the largest castle in the world, by land area. Then the Kings of Poland took over and reigned here for 300 years until the first partition of Poland in 1772. The last rulers of Malbork castle were the Prussians.
The castle fell gradually into decline and it was even severely damaged at the end of WW2. After the war, they made serious efforts to reconstruct and restore the castle to its former glory. The result is spectacular and we are all welcome to visit the present-day museum. Malbork Castle has even become a UNESCO World Heritage Site. Read more about the history and my visit in this article. It starts like this: The Castle Museum at Malbork is one of the greatest historical attractions in Poland and a UNESCO World Heritage Site.
