The Temple of Artemis (Greek: Ἀρτεμίσιον Artemision), also known less precisely as Temple of Diana, was a Greek temple dedicated to Artemis completed— in its most famous phase— around 550 BC at Ephesus (in present-day Turkey). Though the monument was one of the Seven Wonders of the Ancient World, only foundations and sculptural fragments of the temple remain. There were previous temples on its site, where evidence of a sanctuary dates as early as the Bronze Age. The whole temple was made of marble except for the roof.
The new temple antedated the Ionic immigration by many years. Callimachus, in his Hymn to Artemis, attributed the origin of the temenos at Ephesus to the Amazons, whose worship he imagines already centered upon an image. In the seventh century the old temple was destroyed by a flood. The construction of the "new" temple, which was to become known as one of the wonders of the ancient world, began around 550 BC. It was a 120-year project, initially designed and built by the Cretan architect Chersiphron and his son Metagenes, at the expense of Croesus of Lydia.
