Map showing Jarjaraya in relation to other contemporary sites in the region
Jarjarāyā was a city of medieval Iraq, surrounded by a meander of the Tigris. Capital of the district of Lower Nahrawan, it was inhabited by Persian nobles, according to Ya'qubi. This has been taken to assume that Jarjaraya was founded in the Sasanian period, if not earlier. By the time of Yaqut al-Hamawi in the early 1200s, however, the town was in ruins. Archaeological evidence suggests that the site was abandoned by the end of the Abbasid period.
