Archeologists have found ancient coins on which the lighthouse was depicted, and from them deduced that the structure had three tiers: a square level at the bottom, an octagonal level in the middle and a cylindrical top. Above that stood a 16-foot statue, most likely of Ptolemy II or Alexander the Great, for whom the city was named. Although estimates of the lighthouse’s height have ranged from 200 to 600 feet, most modern scholars believe it was about 380 feet tall
