The main one is Petra, a town carved into hillsides 2800 years ago. Coming out of the gorge you won’t believe your eyes as you come across the Treasury, Al-Khaznah, which is several storeys high. Altogether there are 800 buildings from the height of the Nabataeans’ time, 2000 years ago. Over time Petra’s importance as a commercial centre diminished and the town was abandoned. Petra was rediscovered in 1812 and is counted today as one of the “New Seven Wonders of the World”.
