'The 'Castle Across the Way is a rundown castle near Hell Hall. It is the residence of The Evil Queen and formerly Evie. Evil Queen was forced to live there when Maleficent banished Evil Queen and Evie there when Maleficent learned that Mal was the only child on Isle of the Lost not invited to Evie's sixth birthday party. Lacking servants, and because she cared too much about her appearance, the Evil Queen let the castle fall into disrepair. It is implied that the castle is big enough to get lost in as Evie noted she and her mother never strayed too far from the center of the castle; this also implies their rooms were close to the kitchen. Vultures served as the only means for which items were gotten for the Evil Queen and her daughter during that decade. It is also down the street from Hell Hall.
In Return to the Isle of the Lost: A Descendants Novel, its basement is used as the headquarters of the Anti-Heroes Club because Yen Sid believes it is the last place anyone would look.
