Petra (located just off the town of Wadi Musa) is truly one of the most marvelous gems among all ancient sites. The rose-red city carved out of rocks was naturally protected by the walls of the gorge from one side and rocky mountains from the other. The ancient civilization of Nabataeans that settled in Petra was highly advanced, it managed to achieve something not common in the history of humanity - peaceful coexistence with foreign cultures that enabled to create trade routes and brought considerable wealth to the area.
