Al-Hijr Archaeological Site or Madâin Sâlih in Saudi Arabia merits more attention than it receives.
The Nabateans were an Arab people that once ruled large swaths of modern-day Saudi Arabia and the Levant, leaving impressive architectural remnants as a reminder of their civilization.
Jordan's Petra, or Raqmu as the Nabateans called it, was once a flourishing cultural hub for the ancient people. But, Petra isn't the only impressive city left as evidence of the civilization.
The ruins of Al-Hijr date from the first century B.C. to the first century A.D. It is the first UNESCO World Heritage site to be inscribed in Saudi Arabia. "With its 111 monumental tombs, 94 of which are decorated, and water wells, the site is an outstanding example of the Nabataeans’ architectural accomplishment and hydraulic expertise," according to UNESCO.
