The Red Queen's Castle is made out of hearts and shares the same color scheme as the Queen of Hearts card. There are a few problems with the animated geography of the castles location where as, in one scene there is a moat of heads surrounding the castle with the minor draw bridge connecting them both, and in another it's just a rock and dirt path.
The Throne Room is where all of the Red Queen's subjects come to greet her. The throne room is a long corridor with large red pillars reaching up to the ceiling. The throne is a small red heart shaped chair pushed back into a small indent with curtains on either side and a large stained glass window designed with hearts. There are stained windows on the sides of the room giving an illusion of a more spacious feel. The back wall of the entrance has a mural of the Red Queen on the Jabberwocky fighting off a gryphon. The middle section of the floor is checkerboard pattern covered by a red carpet leading up to the heart shaped stairs where the throne is placed. There are two doors on either side of the back wall.
The courtyard is filled with red rose bushes and a crocket game already set up. This is the only place in the castle that shows liveliness.
This room is like any other room except it is filled with fashion materials and hat manikins.
Red Queen's Chamber
This room is dimly lit with a huge balcony and presumably where the Red Queen sleeps.
