Petra is the jewel of South Jordan, a unique 2,000-year-old rock-carved city. Carved entirely into the rose-red cliffs, the remains of the once lost Nabataean city of Petra include temples, Roman theaters, monasteries, houses and roads. Petra flourished for over 400 years around the time of Rome and Christ, until it was occupied by the Roman legions of the emperor Trajan in 106 A.D.
