The generic term desert castle is not ideal, since it artificially separates similar quṣur according to their location. Jordan possesses at least one urban Umayyad qaṣr: the Amman Citadel. While the majority of quṣur are located in Jordan, examples can also be found in Syria, the West Bank and Israel, either in cities (Jerusalem, Ramla), in relatively green areas (al-Sinnabra, Khirbat al-Minya), or indeed in the desert (Qasr al-Hayr al-Gharbi and Qasr al-Hayr al-Sharqi, Jabal Sais, Hisham's Palace). The more isolated desert castles built in arid regions, are chiefly located on the ancient trade routes connecting Damascus with Medina and Kufa or adjacent to a natural oasis.
