Environ-recognition studies have led to the discovery of yet another 20 historical hills near the World Heritage-listed Chogha Zanbil ziggurat, south of Iran.

Following the discovery and documentation of 70 hills (Tappe) in the area, mainly carried out to boost tourism attractions, Iranian archaeologists have managed to find out 20 other ancient sites. “The hills are all related to the ziggurat, because the earthenware unearthed in them give the clearest indication,” said Hamid Fadaei, an archaeologist and lecturer with the project.

He added, however, it was too early and premature to name these newly-found hills, though they will be soon organized for further studies.

Chogha Zanbil is situated in southwest Iran about 40 km southeast of the ancient city of Susa. It was built on a plateau above the banks of the Dez River. The complex consists of a magnificent ziggurat (the largest structure of its kind in Iran), temples, and three palaces. The site was added to UNESCO's World Heritage List in 1979.
