King Stefan's Castle (sometimes referred to as Sleeping Beauty's Castle), is the residence of King Stefan, his family, his servants, and his people. It is also the place where the kingdom was celebrating Princess Aurora's birth when Maleficent, the Dark Fairy of the Forbidden Mountain, suddenly bursts in and blamed Stefan, his family, and his people for not inviting her to the infant princess's christening. It was also the target of a sleeping spell by the Three Good Fairies, so that all the residents would only awake when the spell placed on Aurora can be broken by true love's kiss. Later, when breaking the curse on Aurora with True Love’s Kiss, Prince Phillip freed all the residents of the kingdom from their eternal slumber, including his father King Hubert, King Stefan, and Queen Leah.
