The tower castle is made of white-gray stones. It has five chambers with blue conical roofs. A moat surrounds the castle, with a drawbridge to cross. The drawbridge can be lifted upwards. One of the castle's rooms is a cell that princesses Uniqua and Tasha were locked in for years. The other rooms include a space with video surveillance monitors and a hallway filled with laser beams that trigger alarms.
The castle has appeared in one episode of The Backyardigans: "Break Out!" from season four.
