The castle's exterior is dark gray. It has five visible windows and many different chambers with conical roofs. Inside, there are gray walls made of stone and gray flooring made of tiles. The front entryway leads to several flights of stairs that can collapse. On each staircase is a sign with a message that warns the reader not to climb the stairs.
The vampire's castle has appeared in two episodes of The Backyardigans. It is first seen in "Scared of You" from season two. It can also be seen in a painting in "Who Goes There?" from season three.
