Petra, the world wonder, is without a doubt Jordan’s most valuable treasure and greatest tourist attraction. It is a vast & unique city. Carved into the rock face by the Nabataeans. an industrious Arab people who settled here more than 2000 years ago, turning it into an important junction for the silk, spice and other trade routes that linked China, India and southern Arabia with Egypt, Syria, Greece and Rome. Petra has been a world heritage site since 1985. The best times to view the Treasury are when the sun strikes it directly. Between 9 and 11am, and late in the afternoon, around 5 or 6pm, when the whole facade gets a reddish-pink glow from the walls all around. And around 8:30pm you might assist to Petra’s night show (available Monday, Wednesday & Thursday). A fascinating sight to be a part of.
