The Reverse Castle is an upside down castle that appears through the clouds after receiving the Holy Glasses and releasing Richter Belmont from Shaft's dark spell. It has the same map layout as the original castle (but upside down) and has different color schemes, area names, enemies and bosses. Entering this castle will reveal a new map, and expand the map coverage beyond 100%. This is where Alucard must face his father Dracula in order to obtain one of the possible good endings in Symphony of the Night. The player can still traverse both this and the normal castle through the topmost room of the Castle Keep.
