The Mirror Tower is a historical legendary structure that is thought to be invented and constructed by Archimedes. The purpose of the building is to focus sunlight onto an enemy warship by using a mirror. Once enough energy is focused in the mirror, a ray of light would strike the desired target and light the object on fire. The true existence of this structure is historically disputed since there is little evidence that it actually exists. The Mirror Tower in the game is an over-powered version and exaggerated version of the actual tower.
