The Temple of Artemis or Artemision (Greek: Ἀρτεμίσιον; Turkish: Artemis Tapınağı), also known as the Temple of Diana, was a Greek temple dedicated to an ancient, localised form of the goddess Artemis (equated with the Roman goddess Diana). It was located in Ephesus (near the modern town of Selçuk in present-day Turkey). By AD 401 it is believed it had been ruined or destroyed.^[1] Only foundations and fragments of the last temple remain at the site.

The earliest version of the temple (a Bronze Age temenos) antedated the Ionic immigration by many years. Callimachus, in his Hymn to Artemis, attributed it to the Amazons. In the 7th century BC, it was destroyed by a flood.

Its reconstruction, in more grandiose form, began around 550 BC, under Chersiphron, the Cretan architect, and his son Metagenes. The project was funded by Croesus of Lydia, and took 10 years to complete. This version of the temple was destroyed in 356 BC by an arsonist, commonly thought to have been a madman named Herostratus.

The next, greatest, and last form of the temple, funded by the Ephesians themselves, is described in Antipater of Sidon's list of the world's Seven Wonders:

I have set eyes on the wall of lofty Babylon on which is a road for chariots, and the statue of Zeus by the Alpheus, and the hanging gardens, and the colossus of the Sun, and the huge labour of the high pyramids, and the vast tomb of Mausolus; but when I saw the house of Artemis that mounted to the clouds, those other marvels lost their brilliancy, and I said, "Lo, apart from Olympus, the Sun never looked on aught so grand".^[2]

The fame of the Temple of Artemis was known in the Renaissance, as demonstrated in this imagined portrayal of the temple in a 16th-century hand-colored engraving by Martin Heemskerck.

The Temple of Artemis (artemisia) was located near the ancient city of Ephesus, about 75 kilometres (47 mi) south from the modern port city of İzmir, in Turkey. Today the site lies on the edge of the modern town of Selçuk.

The sacred site (temenos) at Ephesus was far older than the Artemision itself. Pausanias was certain that it antedated the Ionic immigration by many years, being older even than the oracular shrine of Apollo at Didyma.^[3] He said that the pre-Ionic inhabitants of the city were Leleges and Lydians. Callimachus, in his Hymn to Artemis attributed the earliest temenos at Ephesus to the Amazons, legendary warrior-women whose religious practise he imagined already centered upon an image (bretas) of Artemis, their matron goddess. Pausanias believed that the temple pre-dated the Amazons.^[3]

Pausanias's estimation of the site's antiquity seems well-founded. Before World War I, site excavations by David George Hogarth seemed to identify three successive temple buildings. Re-excavations in 1987–1988 and re-appraisal of Hogarth's account^[a] confirmed that the site was occupied as early as the Bronze Age, with a sequence of pottery finds that extend forward to Middle Geometric times, when a peripteral temple with a floor of hard-packed clay was constructed in the second half of the 8th century BC.^[b] The peripteral temple at Ephesus offers the earliest example of a peripteral type on the coast of Asia Minor, and perhaps the earliest Greek temple surrounded by colonnades anywhere.

In the 7th century BC, a flood^[4] destroyed the temple, depositing over half a meter of sand and flotsam over the original clay floor. Among the flood debris were the remains of a carved ivory plaque of a griffin and the Tree of Life, apparently North Syrian, and some drilled tear-shaped amber drops of elliptical cross-section. These probably once dressed a wooden effigy (xoanon) of the Lady of Ephesus, which must have been destroyed or recovered from the flood. Bammer notes that though the site was prone to flooding, and raised by silt deposits about two metres between the 8th and 6th centuries, and a further 2.4 m between the sixth and the fourth, its continued use "indicates that maintaining the identity of the actual location played an important role in the sacred organization".^[5]

The new temple was sponsored at least in part by Croesus,^[6] who founded Lydia's empire and was overlord of Ephesus.^[c] It was designed and constructed from around 550 BC by the Cretan architect Chersiphron and his son Metagenes. It was 115 m (377 ft) long and 46 m (151 ft) wide, supposedly the first Greek temple built of marble. Its peripteral columns stood some 13 m (40 ft) high, in double rows that formed a wide ceremonial passage around the cella that housed the goddess's cult image. Thirty-six of these columns were, according to Pliny the Elder, decorated by carvings in relief. A new ebony or blackened grapewood cult statue was sculpted by Endoios,^[d] and a naiskos to house it was erected east of the open-air altar.
