Chogha Zanbil means basket hill. It holds the remains of the world Ziggurat (a massive ancient solid adobe structure, it has stepped pyramid form with a temple on top for worship and built in ancient Mesopotamia). It was built about 1250 BC by the king Untash-Napirisha, mainly to honor the great god Inshushinak (Elamite deity). Now it is the most intact existing ziggurat in the world. Chogha Zanbil located in Khouzestan, between Ahvaz and Susa, and it lies approximately 42 km (26 mi) southeast of Dezfoul.
This wonderful 3300 year old temple amazes every visitor by its grandeur despite its simplicity. Inscriptions carved on walls talk to people and it seems they try to convey messages from ancient culture and art of Elamite great people to us and reflect the great ancient Persia.
Fortunately ziggurat is situated in the middle of desert, so it is not covered and hidden by sky-scrapers and towers of modern city, there are just Dez River and sugarcane farms around it. This ziggurat testifies great achievements of Persian architecture.
The area was destroyed in 640 BC and abandoned and later got covered by sands carried by the river floods. The locals called it a sand hill without knowing what was inside it for almost 2500 years. Chogha Zanbil was later excavated by Roman Ghirshman during the period from 1951 to 1961. The site was added to UNESCO World Heritage List in 1979.
