Petra lies in the southern part of Jordan. Some 2,000 years ago, it was the capital of the Nabatean Kingdom. It was located on an important trade route that connected the north, south, east, and west.
Many merchants from different countries, some from as far away as China or India, often stayed in Petra because it was on the way to their final destinations, such as Egypt or Rome. That is why Petra was a rich trading center. The merchants who stopped by Petra dealt in spices, silk, and other precious goods.
The Nabateans were experts in water engineering. They created an excellent water supply system throughout the city. Petra was an oasis for the merchants after their long, hard journey across the desert.
