Located 100 kilometers south east of Amman and 63km direct distance from Al-’Azraq, Qasr Tuba was built by al-Walid II in the 8th century AD, but like Mushatta, it was never completed. The size of the palace is 140x72m, and consists of two equally sized square structures connected through a passageway with an entrance. The palace exterior wall has 14 semi-circular towers. Within the palace lies a courtyard surrounded by living quarters. The palace is reminiscent of Al-Mushatta, in terms of building materials (stone and brick), vaulted roofing, and decorations on doorways, and hence it is most likely that they were contemporary to each other. The palace has three deep wells, pools for livestock watering and complex water-raising systems considered unusual for its time.
