The Aqaba Castle or Aqaba Fort, also known as the Mamluk Castle of Aqaba, Jordan, is a Mamluk and Ottoman fortified caravanserai on the pilgrimage route to Mecca and Medina which, in its current form, dates back mainly to the 16th century. In the century preceding the First World War, it was used to a larger degree as a military stronghold.
In July 1917, the fortress was witness to a victory of the Arab Revolt, when this heavily defended Turkish stronghold fell to an Arab camel charge. Lawrence of Arabia rode triumphantly from here to Cairo to report the good news to General Allenby. The port of Aqaba became a major supply base for the advancing Arab Revolt.
