TEHRAN -- For years, the name “Belad Shapur” attached to the historic city of Dehdasht in southwestern Iran has occupied an uncertain place between written history, local memory and archaeological interpretation. 
Recent excavations, however, are helping to close that gap, with evidence from the site lending new weight to references preserved in medieval texts and Safavid-era documents.
According to Zabihollah Masoudi-Nia, who led the first archaeological excavations in Dehdasht’s historic fabric, the name Belad Shapur is supported by written sources dating from the fourth and fifth centuries AH, as well as documentary evidence from the Safavid period. 
Taken together, these records suggest that the name was not a modern attribution imposed on the ruins, but belonged to the historical identity of the settlement.
The significance of the argument lies in the relationship between textual evidence and the physical remains beneath the modern city. 
Masoudi-Nia says recent archaeological investigations have produced evidence that corroborates the historical sources, strengthening the case for understanding Belad Shapur as a name rooted in the city’s long urban history.
The site itself offers an unusually rich record of Islamic-Iranian architecture. The historic settlement contains the remains of a substantial urban landscape, including religious, commercial, residential and civic structures. 
Its scale and architectural character have made Dehdasht one of the important archaeological sites of southern Iran, while its association with the name Belad Shapur has given the ruins a distinctive 
place in the historical geography of Kohgiluyeh and Boyer-Ahmad.
The wider history of the site also places it within a region where successive political and cultural periods left their mark on urban form. 
Dehdasht reached particular prominence during the Safavid period, when it functioned as an important administrative and commercial center. Surviving remains include bazaars, mosques, caravanserais, baths, religious buildings and residential structures, revealing a city organized around the movement of people, goods and ideas.
The archaeological importance of Belad Shapur therefore extends beyond the question of a name. Its buildings and urban fabric offer material evidence for the development of Iranian city life across successive Islamic periods. 
Comparable archaeological landscapes in southern Iran demonstrate how urban planning and architectural traditions could persist and evolve across political and religious transformations.
