Castle Revolta was Revolta's lair.
Scooby-Doo And The Ghoul School
Revolta kidnapped the girls from Miss Grimwood's Finishing School for Ghouls and held them at her castle, and tried to turn them evil with a spell. Eventually the castle was destroyed in a potion explosion, leaving Revolta and her minions to fall helplessly to the ground far below.
