History
Built from 707-715 AD and located in the Syrian Desert. The location was dependent on the seasonal supply of water which pooled next to the volcano crater. The palace is now just a vestige. The settlement at Jabal Says has existed since 528 AD. According to the historian Jere L. Bacharach, al-Walid I built Jabal Says, likely as a Bedouin summer encampment between his base of operations in al-Qaryatayn and another of his desert forts, Qasr Burqu'.
