ANCIENT WONDER IN RUINS. A single column remains of the Artemisium at Ephesus. Once counted among the Seven Wonders of the World, the Artemisium was a massive temple—the largest building in the Hellenistic world—built for the goddess Artemis. The temple’s foundation, which was 425 feet long and 220 feet wide, supported 127 Ionic columns. Each 60-foot-tall column had a 7-foot diameter. A naval invasion by the Goths in 262 C.E. left the temple in ruins. A sole remaining column of this ancient wonder has been reerected.
