Jordan. Petra. The archeological site is part of the UNESCO world heritage project. The Nabateans were an arabian industrious tribe which settled down in southern Jordan 2000 years ago. Petra is located at the bottom of a spectacular deep gorge surrounded by mountains. After walking down the "Siq", a narrow and long path through a fault due to a prehistoric earthquake, tourists discover the fist building "El Khazneh". Its high façade is carved in the rocks.
