Dayr Murrān was a monastery and village in the western outskirts of Damascus, on the lower slopes of Mount Qasioun, that had been a favored seasonal residence of the Umayyad and Abbasid caliphs in the 7th, 8th and 9th centuries.
The exact location of Dayr Murran has not been identified, though the medieval sources indicate it was situated on the lower slopes of Mount Qasioun near the Bab al-Faradis gate of Damascus.
[1] Dayr Murran was utilized by the Umayyad caliphs as a residence where they could be entertained while overseeing their capital Damascus.
[1] As early as 660, while the Umayyad Mu'awiya I was governor of Syria, his lieutenant Busr ibn Abi Artat mobilized his forces at Dayr Murran for the conquest of Mecca and Medina from Caliph Ali's control.
[3] The future caliph Yazid I (r. 680–683) made improvements to its irrigation systems and was staying there before being dispatched to the Byzantine front in Anatolia by his father, Mu'awiya I.
