"Petra - Magical Land of the Nabataeans" Petra by scpinmd

Petra was first established sometime around the 6th century BC, by the Nabataean Arabs, a nomadic tribe who settled in the area and laid the foundations of a commercial empire that extended into Syria. Despite successive attempts by the Seleucid king Antigonus, the Roman emperor Pompey and Herod the Great to bring Petra under the control of their respective empires, Petra remained largely in Nabataean hands until around 100AD, when the Romans took over. It was still inhabited during the Byzantine period, when the former Roman empire moved its focus east to Constantinople, but declined in importance thereafter. The Crusaders constructed a fort there in the 12th century, but soon withdrew, leaving Petra to the local people until the early 19th century, when it was visited by the Swiss explorer Johann Ludwig Burckhardt.

I plan on putting more pictures in a travelogue soon.

The first of the so called Royal Tombs is the Urn Tomb. This tomb is built high on the mountain side, and requires climbing up a number of flights of stairs. It is suggested that this is the tomb of Nabataean King Malchus II who died in 70 AD. or possibly the tomb of Aretas IV.
