Eight archaeological sites situated in three geographical parts in the southeast of Fars Province: Firuzabad, Bishapur and Sarvestan. These fortified structures, palaces, and city plans date back to the earliest and latest times of the Sassanian Empire, which stretched across the region from 224 to 658 CE. Among these sites is the capital built by the founder of the dynasty, Ardashir Papakan, as well as a city and architectural structures of his successor, Shapur I. The archaeologic landscape reflects the optimized utilization of natural topography and bears witness to the influence of Achaemenid and Parthian cultural traditions and of Roman art, which had a significant impact on the architecture and artistic styles of the Islamic era.
Iranian officials had submitted the related dossier to the International Council on Monuments and Sites and the International Union for Conservation of Nature in July 2017.
