Huge stone circles in the Middle East have been imaged from the air, but researchers remain puzzled as to why they exist, and who made them. 11 Big Circles dot the landscape across Jordan and Syria. They date back at least 2,000 years, but may even be pre-historic, created in a time before the invention of writing. They’re very large, some of them approximately 1,300 feet in diameter, and are composed of short, stone walls built from local rocks. Researchers say the circles would have required some planning, as many of the circles are very precise. It was likely there was some sort of “architect” to head up each project. David L.
