Discovered in 1979 by the inspector of antiquities in Petra, this room is a lovely example of a Nabataean residence. The cave probably formed one room within a larger Nabataean housing complex made up of several adjacent caves with six rooms. The walls of the cave are covered with stucco painted with drawings of doorways framed by pale blue bands on an orange or dark red background. In the architectural fresco on the south and west walls of the Wadi as-Siyyagh room, the doorways are topped with cornices and pediments. A winged sphinx—probably an influence from Greek mythology—stands above one doorway. The ceiling of the cave was plastered and had a circular, molded central roundel. The combination of Nabataean, Greek, and Roman influences in the frescoes and architectural features highlights the diverse cultural interactions that occurred in this region during ancient times. Part of the Wadi as-Siyyagh fresco was cleaned and restored in 1980. The Painted Room of Wadi as-Siyyagh is dated to the 1st century BC.
