A tell site in northwest Iran occupied off and on from the Early Bronze Age to the Sassanian period. The earliest occupation is dated to the 6th millennium BC, but its most important material comes from the Elamite period of the 15th-13th centuries BC. A royal tomb of c 1500 BC containing 21 skeletons, some covered in red ochre, is an early example of a vaulted tomb. This tomb was connected by a stairway to the main temple which contained many simple burials, some in urns. Fragments of inscribed stelae in cuneiform in the 14th-century BC Elamite language have provided details of the temple economy. In the 8th century BC, the mound became an Urartian citadel with an attached lower town. It was destroyed either by Sargon II in 714 BC or by the Cimmerians. The site was reoccupied in the Sassanian period: a town wall and numerous graves of this period are known.
