It is a yellow medieval-styled fortress with green rooftops on the round spires. Flags with the symbol of Shrek's Kingdom constantly blows high in the wind.
The castle itself is placed on a cloud in the air, and the only way to access its gate is by following a rainbow path from the lush park below, which is surrounded by a set of yellow walls.
Additional rainbow paths from the fortress lead to two towers, both isolated on their own cloud.
