Khadra Palace
The Khadra Palace, known in Arabic as Qubbat al-Khadra (قبة الخضراء, lit. 'the Green Dome'), was a residence of the Umayyad caliphs in Damascus. It was founded by the first Umayyad caliph, Mu'awiya I (r. 661–680), while he was governor of Syria under Caliph Uthman (r. 644–656). The Khadra Palace consisted of a series of interconnected buildings, including the caliphal residence, stables, mint and prison, situated directly behind the Umayyad Mosque. Little information is available describing the structure, other than the green color of its dome, its construction from baked brick, timber and marble pavement and its setting amid gardens.
It remained in official use after the fall of the Umayyads and transfer of the caliphate to Iraq by the Abbasids in 750. It was probably destroyed during the Fatimid period in the 10th or 11th century and there are no known traces of the structure.
