Situated in the Wadi Rum canyon desert, Petra is now one of the seven wonders of the world and a UNESCO World Heritage Site.
The ruins of Petra are located in Jordan, in the Middle East. It is an impressive ancient city whose architecture is entirely carved into the rock. The date of the city's emergence remains unknown, but it became the capital of the Nabate Empire around the 1st century BC. The archaeological site was discovered in 1812 by the Swiss explorer Johann Ludwig Burckhardt.
