In a report provided by UNESCO on Jul, 2, 2018, eight Sassanian archaeological sites have been officially identified as heritage sites. These are located in three geographical regions in Iran’s Fars Province: Firuzabad, Bishapur and Sarvestan.

These UNESCO sites are Sassanian fortified structures, palaces, as well as city plans. These are chronologically dated from the early to late Sassanian eras (224-651 CE).

These sites include the original capital of Ardashir Papakan (founder of the Sassanian dynasty), as well as the city and architectural structures of his son and successor, Shapur I.

As averred further by UNESCO:

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.
