Iran contains Chogha Zanbil, a UNESCO-listed Elamite ziggurat.
Chogha Zanbil is an ancient religious complex in Iran’s Khuzestan Province. The Elamite king Untash-Napirisha founded it around 1250 BCE near the ancient city of Susa. Its central monument is a large ziggurat dedicated chiefly to the gods Inshushinak and Napirisha.
The structure was built from mud bricks, with many bricks carrying inscriptions in the Elamite language. Unlike Mesopotamian ziggurats that stood within major cities, Chogha Zanbil was established as a sacred center outside Susa. The site preserves temples, walls, gates, and water-management features.
Chogha Zanbil is sometimes mistaken for a Mesopotamian monument in modern Iraq because ziggurats are strongly associated with Iraq. It is actually in southwestern Iran and was one of the first Iranian sites added to the UNESCO World Heritage List.
