“ Chogha Zanbil is an ancient Elamite complex in the Khuzestan province of Iran. It is one of the few extant ziggurats outside of Mesopotamia. It lies approximately 25 kilometeres west of Dezfoul, 45 kilometres south of Susa and 230 kilometres north of Abadan by way of Ahvaz, which is 120 kilometres away. It measures 105x105 meters and was probably 52 meters high. It was to be the center of a new town, which was to become the king’s residence, but was never quite finished. The town measured about one square kilometer and was surrounded by a four kilometer wall.
It was built about 1,250 BC by the king Untash-Napirisha, mainly to honor the great god Inshushinak. Its original name was Dur Untash, which means ‘town of Untash’, but it is unlikely that many people, besides priests and servants, ever lived there. The complex is protected by three concentric walls which define the main areas of the 'town’. The inner area is wholly taken up with a great ziggurat dedicated to the main god, which was built over an earlier square temple with storage rooms also built by Untash-Napirisha. The middle area holds eleven temples for lesser gods. It is believed that twenty-two temples were originally planned, but the king died before they could be finished, and his successors discontinued the building work. In the outer area are royal palaces, a funerary palace containing five subterranean royal tombs….” http://historicaliran.blogspot.co.uk/2009/12/chogha-zanbil.html
