Ancient Lava Field Walls Mystify Archaeologists in Saudi Arabia
Archaeologists are baffled at the discovery of a mysterious ancient site in the inhospitable lava fields of western Saudi Arabia.
Some 400 structures, known as ‘gates’ due to their long, rectangular shape, have been found in Harrat Khaybar, a volcanic field north of Medina.
Writing in the journal Arabian Archaeology and Epigraphy, David Kennedy of the University of Western Australia says he believes the structures date back thousands of years to a time when the landscape was much less barren.
The academic also compared the find to similar sites found in neighboring Jordan, hinting that local folklore might hold clues to what they are and why they were built.
The gates were first discovered by an amateur Saudi heritage group, who used satellite imagery from Google Earth to mark places of interest. The group, known as the ‘Desert Team,’ then visited the sites before publishing pictures and survey data to its website.
Low with rough-built walls, the structures measure between 50-150 meters (160-500ft) in length, with the longest one measuring 500 meters (1,700ft), around the size of a football field.
