Recently, the massive stone circles located in the Middle East have been photographed, revealing the detailed structures that have long baffled the archaeologists.

In Jordan, researchers took the aerial photographs of eleven monstrous stone circles that were built long ago. The largest circle found to have a diameter of more than 1,300 feet.

But still, archaeologists are uncertain of exactly why these stone circles were built, but hopes are high that studying them from the air will help shed some light on the mystifying constructs. It has been believed that the Big Circles were once associated together based on the similarity of the rings share with each other.

The circles were built of stone in low walls and have shown no proof of gaps or openings. With low walls, researchers believe that it’s a safe bet that anyone who wanted to get in these circles would have simply hopped over one of the walls. Though, the mystery of why these circles were built still remains unsolved.

After analyzing the images, researchers revealed that the circles were constructed about 2,000 years ago. Though, this date is a contentious one; some of the researchers think that the rings could be even older, pre-dating agricultural civilization by several thousand years.

An archaeology professor at University of Western Australia and the lead researcher who involved in investigating these sites David Kenney said, “It’s vital to collect as much information on these sites as possible in order to make them known to the scientific community and the public. We are working together with aerial photographers and also gathered satellite data from websites such as Google Earth to glean as much information as possible from the sites.”

Kennedy, an old hand at archaeological research in the region, is no stranger to aerial photography. Once he was the co-director for the Aerial Photographic Archive for Archaeology in the Middle East.
