At the top of the Prison Tower inCastlevania: Belmont's Curse, you will find the Warrior, one of the initial bosses you must fight to open the gate to the catacombs. To access the floors in the lower part, you must use the adjacent buildings to lower the gates that serve as platforms and swinging spots. However, to pass over the Upper Tower and reach the Roof of the Tower area, where the boss awaits, your acrobatic skills won't help you.
