The desert castles or qasrs are often called Umayyad desert castles, since the vast majority of these fortified palaces or castles were built by the Umayyad dynasty in their province of Bilad ash-Sham, with a few Abbasid exceptions. The desert castles of Jordan represent a prominent part of this group of buildings, with most Umayyad "desert castles" being scattered over the semi-arid regions of north-eastern Jordan, with several more in Syria, Israel and the West Bank (Palestine), and just one Abbasid exception in Iraq.
