About 2,000 years ago, an ancient civilization called the Nabataean carved proof of their existence into the soft sandstone rocks in Petra, Jordan.
This city of stone is a place defies time itself, and after all these years continues to inspire wild myths and legends. You’ll probably remember this location from the movie Indiana Jones and the Last Crusade.
The tremendously grand scale of these structures is absolutely mind boggling. How did these people manage to carve such intricate designs into these rock cliffs?
While the Nabataean empire was still standing, Petra was a bustling city and a frequented stop on the caravan trade route. In A.D. 106, Rome formally took control over the region.
In 1985, the Petra Archaeological Park was declared a UNESCO World Heritage site, and in 2007 it was named one of the new seven wonders of the world.
Today, this exotic location remains, to some extent, an unexplained mystery. So far, only about 15 percent of the city has been discovered; what remains is still concealed underground. Many believe there is still a massive hidden treasure just waiting to be found beneath the surface.
