Considered an architectural wonder of the ancient world, the Artemision of Ephesus was built entirely of marble and was the largest of its kind in the Hellenic world. The temenos contained at least four temple phases, built centuries apart, one of top of the remains of the previous temple. The first temple was built circa 700 BC. The second temple was built circa 600 BC, probably by the tyrant Pythagoras. Later, circa 560-550 BC, the Archaic monumental temple was built. This dipteral Ionic temple, measuring 55 by 115 meters, was the first monumental edifice to be made entirely of marble. It had 127 columns, a long and narrow cella and a deep pronaos. It was designed by Cretan architects Chersiphron of Knossos and his son Metagenes and by architect Theodoros of Samos. Later Artemision, built circa 334-250 BC, was considered an architectural marvel. This exquisitely ornamented Temple had the same dimension, ground and column plan as the previous Temple phase. However, it had a very high, 13-stepped crepidoma on which it was built and it had no naiskos. The Temple was destroyed by the Goths circa 263-268 AD. Today only a single column and some ruins are what remain on site.
