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 very 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.

Jordan, officially the Hashemite Kingdom of Jordan, is a country in the Southern Levant region of West Asia. Jordan is bordered by Syria to the north, Iraq to the east, Saudi Arabia to the south, and the occupied Palestinian territory of the West Bank and Israel to the west. The Jordan River, flowing into the Dead Sea, is located along the country's western border. Jordan has a small coastline along the Red Sea in its southwest, separated by the Gulf of Aqaba from Egypt. Amman is Jordan's capital and largest city, as well as the most populous city in the Levant.
