Qasr Amra ( / ALA-LC: Qaṣr ‘Amrah), often Quseir Amra or Qusayr Amra, is the best-known of the desert castles located in present-day eastern Jordan. It was built early in the 8th century, sometime between 723 and 743, by Walid Ibn Yazid, the future Umayyad caliph Walid II, whose dominance of the region was rising at the time. It is considered one of the most important examples of early Islamic art and architecture. The discovery of an inscription during work in 2012 has allowed for more accurate dating of the structure.
