Chogha Zanbil is an ancient worshiping place built around 1250 BC during the Elamite period. This monument is the remaining part of the ancient city of Dorantash and is located near the magnificent city of Susa in Khuzestan Province. The old building built by the king Untash-Napirisha mainly to honor the great god, Inshushinak. This may be attributed to the possibility that the ancient city was never quite finished, as Untash-Napirisha did not live long enough to see his work completed. Chogha Zanbil is considered as the first site registered in the UNESCO’s World Heritage List and also the orientalists know this place as the first religious site in Iran.
Chogha Zanbil is the ancient name of this structure and a local word composed of two words of "Chogha" (in Lorri language means "hill") and Zanbil (meaning "basket"). This word is a reference to the location of the temple over the hills and simulates it to an inverted basket. Several bull sculptures of Inshushinak were found within the complex, which served the royal families of Elam as a place both of worship and of interment. In addition, a variety of small artifacts were recovered, including a collection of Middle Elamite cylinder seals. A building on the grounds contains five vaulted underground tombs, within four of which are cremated remains, and there is one uncremated corpse.
