UNESCO is scheduled to present its world heritage certificate to the ancient site of Persepolis in the southern Iranian province of Fars.

United Nations Educational, Scientific and Cultural Organization (UNESCO) will award the certificate to Iran during a ceremony to mark the country's efforts in safeguarding the ancient site, press tv reported.
The Achaemenid site of Persepolis was registered on the UNESCO World Heritage List in 1979.

Founded by Darius I in 518 BCE, Persepolis was the capital of the Achaemenid Empire. It was built on an immense half-artificial, half-natural terrace, where the king of kings created an impressive palace complex inspired by Mesopotamian models.

The importance and quality of the monumental ruins make it a unique archaeological site.
According to the United Nations Information Centre (UNIC), certificates will be granted to Iran's Armenian Monastic Ensembles, Soltanieh Dome, Takht-e-Suleiman, and Choqa Zanbil.
