Famous for its buildings and monuments carved out of red sandstone cliffs, Petra was an artificial oasis in the middle of the desert, strategically located at the crossroads of trading routes. Today it is a World Heritage Site, and one of the New Seven Wonders of the world. Photo in thumbnail image by Diego Delso. Like this video if you want to see more videos about LANDMARKS!
