Petra was not a city of the dead. In addition to tombs and temples in the canyons, Petra had whole neighborhoods of private and public buildings. One of the most prominent such public buildings was Greco- Roman Amphitheatre carved in the surrounding cliffs. Original structure was carved by the Nabataeans before the arrival of Romans. Original smaller structure was used for religious purposes. Once the Tenth Roman Legion arrived, they turned small theater into a magnificent amphitheater. Petra Amphitheatre was able to seat over 8,000 spectators during its heyday. This structure was used for music contests, performances and religious rituals.
