Built: About 550 B.C.
Location: In Greek city of Ephesus, on west coast of modern Turkey
History: The great Ionian city of Ephesus was chosen as the site for one of the largest and most complex temples built in ancient times. The Temple of Artemis (Diana) had a marble sanctuary and a tile-covered wooden roof.
Conceived by architect Chersiphron and his son, Metagenes, the temple's inner space featured a double row of at least 106 columns, each believed to be 40 to 60 feet high. The foundation was approximately 200 feet by 400 feet.
The original temple burned in 356 B.C. and was rebuilt on the same foundation. Fire devastated the second temple in 262 A.D., but its foundation and some debris have survived. The British Museum in London counts some of the second temple's sculptures among its treasures.
