National Geographic is set to premiere Lost Treasures of Arabia: The Ancient City of Dadan, a documentary on the ancient history of AlUla, a historical city in the northwest region of Saudi Arabia and UNESCO World Heritage site, on March 13. 

Directed by Dirk Verheye and Inti Calfat, the documentary explores the rich history and cultural significance of AlUla, which is home to some of the world’s most ancient archaeological sites, including the ancient city of Dadan and the rock formations of Mada’in Saleh.

This 44-minute documentary tells the rich history of the Dadanite and Lihyanite kingdoms that existed over 2000 years ago, and explores why the Dadanite kingdom disappeared.

Today, AlUla is a popular tourist destination, attracting visitors from all over the world. The city also houses the Hegra Archaeological Site, which features over 100 tombs dating back to the first century AD.
