iranian cities after the collapse of sasanian kingdom: a case study of darabgird

darabgird is one of the ancient cities in fars province. according to iranian mythology, darab shah (dariush, the great) found the city in the achaemenid period. but, due to the fact that 1.21% of total ceramics gathered from the city belongs to the parthian era, we can accept that the city remained in use since parthian period to the islamic era. data analysis shows that the city had a strong and intensive settlement during sasanians, after the arab conquest and the collapse of pars province, some changes occurred in the function of urban spaces. accordingly, the main settlement shifted to the north of the city. apparently, the southern half of the city was abandoned in islamic era. finally, according to some other early islamic cities, apparently in this period, the main settlement of the city shifted to outside of sasanian city (in this case, north of the sasanian fortifications) and we should survey this area to discover available evidences of this period. unfortunately, this area is presently being used for agricultural purposes.
