Scientists discovered about 400 ancient stone gates in Saudi Arabia

Vastavam web: Scientists have discovered about 400 previously undocumented stone structures known as ‘Gates’ in Saudi Arabia with the help of Google Earth imagery.While Saudi Arabia is largely thought of as barren mountains and desert, it was also home to an immense number of archaeological sites that were yet to be identified, recorded and mapped, said David Kennedy, researcher at University of Western Australia.”I refer to them as Gates because when you view them from above they look like a simple field gate lying flat, two upright posts on the sides, connected by one or more long bars,” he said.

They do not look like structures where people would have lived nor do they look like animal traps or for disposing of dead bodies. It is a mystery as to what their purpose would have been, researchers said.Since 1997, Kennedy has flown in helicopters over Saudi Arabia’s neighbour Jordan, photographing tens of thousands of stone-built structures scattered over its lava field or ‘harrat’.Not much is known about the people who built the edifices, but they are thought to have constructed them 2,000 to 9,000 years ago, researchers said.
