Bran's Castle is also called the Castle of Dracula, though both the count of history and legend may not have had much to do with it. The historic count may have lived there for a short while, but no one knows for certain. The Castle was built for controlling a trade route from Brasov to Cimpulung Muscel.
The Castle is incredible. Small corridors end up in large rooms. You haven't got a clue where you are and some stairs give you the idea that they lead to nowhere. It really is a must-see.
