Susa 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 5^th millennium BCE until the 13^th century CE. The site bears exceptional testimony to the Elamite, Persian and Parthian cultural traditions, which have largely disappeared.

In 2015 Susa registered as a world Heritage site by UNESCO.

 The remains of the ancient city of Susa bear exceptional testimony to successive ancient civilizations during more than six millennia, as well as having been the capital city of the Elamite and Achaemenid Empires. It contains 27 layers of superimposed urban settlements in a continuous succession from the late 5th millennium BCE until the 13th century CE. Susa is on the most ancient of the sites, where the processes of urbanization crystallized in the late 5th millennium BC. A decade of scientific excavations from 1968 to 1978, and philological works at Susa, also documented the development and changing character of this early urban centre throughout the millennia.
