Description: Built during the late Memlouk era in al Darwishieh near the square of Bab al Jabiah, by the last Memlouk governor of Damascus (Prince Sibai son of Bakhtija) before he was killed in the battle of Marj Dabeq, 1516, defending Damascus against the Ottomans who could occupy the region for more than four centuries . Construction started in 1509 and finished in 1515. To build it Prince Sibai collected stones and pillars of old and neglected mosques, cemeteries and the marbles of the decaying school of Khatoun and from other deteriorating buildings in Damascus, hence the scholars of Damascus called it the Mosques Collection.
