In the middle of The Arabian Peninsula lies the Empty Quarter, or Rub’ al Khali, the world’s largest sand sea. This inhospitable space covers over 225,000 square miles of land, and occupies parts of Saudi Arabia, Oman, Yemen and United Arab Emirates.

The land is unoccupied, save Bedouin tribes, although adventurers frequently attempt and occasionally succeed in crossing it. Thousands of years ago, though, the Empty Quarter may not have been so empty. The area once contained lakes and rivers, and even supported farm crops and livestock.
From 6,000 to 3,000 B.C., ancient civilizations sprung up in this area. Traders came here to trade horses and frankincense, a plant resin used in perfumes and burial ceremonies. Frankincense was as valuable as gold.
The Koran and “A Thousand and One Arabian Nights” share stories of a long-forgotten city, Ubar, renowned for its splendor and wealth. For many years, scientists wondered if this “Atlantis of the Desert” really existed or if it was merely a myth.

In 1992, archaeologists finally uncovered the real Ubar. Using satellite imagery, they found packed down ground marking trade routes used by traders and their burden-laden camels. They suspected any city would lie where these trade routes intersected. Their hunch was right. The scientists did not find a large city as we know it, since most people then lived in tents that have long since disappeared. Instead, they found a fort protected by eight thick walls.
The researchers discovered that the city had been built atop a limestone cavern. The weight of the fort caused the cavern to collapse, and the fort to sink. Soon, the desert sands completely covered the city, leaving no trace that it ever existed.
