We just learned about the Malbork Castle.
Another famous castle is Bran Castle, built in 1300s in Romania.
This castle is sometimes called "Dracula's Castle" because the famous ruler Vlad Țepeș stayed in this castle a few times.
The book Dracula by Bram Stoker is just a made up story, but the writer Bram Stoker used the real person Vlad Țepeș (also known as Vlad the Impaler) as part of his book and made up a story about him being the vampire Dracula.
Vlad was a real person and Dracula was a fake story, but since Vlad stayed in Bran Castle they like to tell stories about this castle!
