Discovered in 1979, this room is a good example of a Nabataean residence.  The cave probably formed one room within a larger housing complex made up of several adjacent caves.  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.  The architectural fresco on the south and west walls of the Wadi as-Siyyagh room indicate that 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.
