[2][3][4] Qasr al-Hallabat is one of the Umayyad complexes collectively known as the desert castles, with Hammam al-Sarah once functioning as its bathhouse.

The windows were probably glazed, as suggested by fragments of flat, coloured glass, and helped control the temperature.

Creswell surveyed and photographed it in 1926, finding the building well preserved, which remained the case until the 1950s, when it was massively pilfered of stones, bringing it close to complete destruction.

[6] Recent work was done by the Spanish Archaeological Mission to Jordan under Ignacio Arce as part of the excavation and restoration project of Qasr al-Hallabat.

[6] Arce studied the ruins, published the results in 2015, and set himself the goal of dismantling the emergency reconstructions of 1974 in order to restore and strengthen the building by using current, balanced preservation procedures.
