A theatre cut from the rock around the first century AD, seating about 8,000 people when built. The lower rows are well preserved; the upper rows are eroded and the stage building is mostly gone, though its foundations remain.
The interesting thing is the construction. Most Roman theatres were built up; this one was cut down. The whole semicircle of seating is single-piece sandstone, and the destruction of earlier tombs that the construction implies tells you something about the speed with which the Nabataeans were Romanising under their later kings.
