English: Chogha Zanbil (also Tchoga Zanbil and Čoġā Zanbīl) (Persian: چغازنبيل; Elamite: Al Untas Napirisa then later Dur Untash) is an ancient Elamite complex in the Khuzestan province of Iran. It is one of the few existing ziggurats outside Mesopotamia. It lies approximately 30 km (19 mi) southeast of Susa and 80 km (50 mi) north of Ahvaz. The construction date of the city is unclear due to uncertain in the chronology of the reign of Untash-Napirisha but is clearly sometime in the 14th or 13th century BC. The conventionally assumed date is 1250 BC. The city is currently believed to have been destroyed by the Neo-Assyrian ruler Assurbanipal in about 645 BC, along with the Elamite capital of Susa though some researchers place the end of occupation in the late 12th century BC.
