The castles, for want of a better description, were built between the 7th Century and 8th Century. The function and use of the buildings has still not been determined. There are different theories concerning their use – they may have been fortresses, meeting places for Bedouins, retreats for nobles, or used as caravanserais. Many seem to have been surrounded by an oasis and to have served as bases for hunting. Today your English speaking driver will take you to 3 fine examples – The Qasr Kharana (Al Kharaneh), Qasr Amra and Azraq Castle (used by Lawrence of Arabia during the Arab Revolt of 1917-18).
