Approximately 1400 meters east of the palace stands the remains of the mosque at Qusayr al-Hallabat. Small in scale, it measures 10.70 by 11.80 meters and is constructed of layered limestone. Inside, two arching riwaqs divide the mosque into three sections. A rounded molding extends the perimeter of the space at the height of 2.10 meters. Similar to Qusayr 'Amra and Qasr Hammam as Sarah, three tunnel vaults support the roof of the structure. Encircling the mosque from the north, west, and east stood a 3.30-meter wide portico
