Located in the south-west of Iran, in the lower Zagros Mountains, the property encompasses a group of archaeological mounds rising on the eastern side of the Shavur River, as well as Ardeshir’s palace, on the opposite bank of the river. The excavated architectural monuments include administrative, residential and palatial structures. Susa contains several layers of superimposed urban settlements in a continuous succession from the late 5th millennium BCE until the 13th century CE. The site bears exceptional testimony to the Elamite, Persian and Parthian cultural traditions, which have largely disappeared.

Susa developed as early as the late 5th millennium BCE as an important centre, presumably with religious importance, to soon become a commercial, administrative and political hub that enjoyed different cultural influences thanks to its strategic position along ancient trade routes. Archaeological research can trace in Susa the most complete series of data on the passage of the region from prehistory to history. Susa appears as the converging point of two great civilisations which reciprocally influenced each other: the Mesopotamian and the Iranian plateau civilisations. Susa’s long-lasting and prominent role in the region, either as the capital of the Elamites, or of the Achaemenid Empire, or as a strategic centre sought by neighbouring powers (e.g., Assyrian, Macedonian, Parthian, Sassanid) is witnessed by the abundant finds, of disparate provenance and of exceptional artistic or scientific interest, and by the administrative, religious, residential and palatial, as well as functional structures and traces of urban layout (e.g., the remains of the Haute Terrasse in the Acropolis, the Palace of Darius in the Apadana, the residential or…
