Mystery of Jordan's Big Circles: Ancient circles baffle archaeologists
A total of eight big circles have been recorded in west central Jordan, between the Wadi el-Hasa and the edge of the Shara escarpment. There is also a second group, made of four Big Circles, just north of Azraq Oasis. Pictured is circle J1, known locally as Qasr Abu el-Inaya. Dating is problematic, but there is often material in or around the circles that originated in the Chalcolithic and Early Bronze Age, between 2,000 to 4,500 BCE.
