Cinderella Castle was created in 1971.

There is no castle "Cinderella's Castle". The castle that is pictured is make believe. The closest one to it is in Germany and is called Neuschwanstien and was built in the 1700's by Ludwig of Bavaria. ( well past the middle ages)
Tokyo Disneyland features Princess Cinderella's castle.
