Excavations at the Umayyad and Early Abbasid Reservoir-Enclosure of ‘Ayn Sawda (Azraq Oasis, Jordan)

Abstract

In the centre of the Azraq oasis in the Eastern Desert of Jordan, there is a long wall previously interpreted as a huge water reservoir that was fed by the ‘Ayn Sawda spring. The site, seen as belonging to the category of the Umayyad “desert castles,” is best known through the many basalt blocks with mortise and tenon joints that were found there, several being carved with figurative representations in bas and high relief. These form an exceptional archaeological collection with no known iconographic parallel. Given the uncertainty of both the function and dating of the structure, between 2013 and 2016, the Azraq ‘Ayn Sawda Reservoir Project (Ifpo) made a topographical plan of the site and an inventory of the carved blocks, and carried out excavations, an architectural study and an assessment of the state of preservation. The results suggest an enclosure delimiting an agricultural area to the west and a water reservoir to the east. It was built in the Umayyad period, somewhere between 664 and 690 AD, and probably reconfigured in early Abbasid times, somewhere between 768 and 900 AD. Excavation also revealed unusual and various building techniques designed for very specific environments. This monument exploited all the possibilities of this rich oasis to enhance the landscape.
