Qasr Tuba
In 1896 Alois Musil, a Czech explorer and Arabist, was cold by the bedouin of Madaba of some old palaces in the desert, adorned with columns, paintings and inscriptions. On his return two years later, he found Qasr at-Tuba, the largest and most remote of a group of desert residences built in the early 8th century under the auspices of the Umayyad caliphs.
