The castle's exterior is mostly gray, with five windows in front. It is made of rectangular stones. Similarly to King Austin's castle, one of the castle's chambers has a conical roof. The roof is red with a single flag on top of it. The other chambers have turrets on top of them. Inside the castle is a large yellow throne, a map, and several stained glass windows.
Queen Tasha's castle has appeared in one episode of The Backyardigans: "Knights Are Brave and Strong" from season one.
