Petra, a historic and archeological city in Jordan, lies on the slope of Mount Hor in a basin among the mountains, with its’ rock cut architecture and water conduits system. Established sometime around the 6th Century BC as the capital city of the Nabateans, being the centre of their caravan trade. Enclosed by towering rocks and watered by a perennial stream, Petra not only possessed the advantages of a fortress, but controlled the main commercial routes which passed through it to Gaza in the west, to Bosra and Damascus in the north, to Aqaba and Leuce Come on the Red Sea, and across the desert to the Persian Gulf. However, the site remained unknown to the Western World until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt.
This city has a lot to tell. After passing some tombs, which are located outside the city, the visitor passes through the SIQ, an immense crack in the Nubian sandstone. It is a winding, one-kilometer-long fissure between overhanging cliffs that seem to meet more than 300 feet overhead. Near the end of the passage, the SIQ, with great style, makes one last turn and out of the gloom in towering brightness appears Petra's most impressive monument, el Khazneh "The Treasury". This is one of the most elegant remains of antiquity, carved out of the solid rock from the side of the mountain, is nearly 140 feet high and 90 feet wide.
Beyond el Khazneh the visitor is surrounded on both sides by hundreds of Petra's carved and built structures, soaring temples, elaborate royal tombs, a carved Roman theater, large and small houses, burial chambers and much more.
