[1][2] Ghirshman spent nearly thirty years excavating ancient Persian archeological sites throughout Iran and Afghanistan.

He was mainly interested in the archeological ruins of Iran, specifically Tepe Giyan, Teppe Sialk, Bagram in Afghanistan, Bishapur in Fars, and Susa.

His studies on Chogha Zanbil have been printed in 4 volumes, and he also led excavation teams at Kharg Island, Iwan-i Karkheh, and the Parthian platforms in Masjed Soleiman, near Izeh, Khuzestan.

Some of his works on Susa have not even been published yet, but have served other archeologists such as Jean Perrot and Hermann Gasche in subsequent follow-up studies in the 1960s and 1970s in Iran.
