[Source] Prince John's Castle is a location in Robin Hood. It is the primary home of Prince John and Maid Marian. The formal owner of this Castle is King Richard, the older brother of Prince John, although a line by Sir Hiss indicated that the castle was owned at some point by John and Richard's mother. A large portion of the castle catches on fire as a result of the Sheriff's recklessness during his final confrontation with Robin Hood.
