PERTH, AUSTRALIA—Jordan’s “Big Circles” were first spotted from airplanes in the 1920s, but little has been learned about them since then. The low walls, often made from uncut stones, would not have kept animals in or enemies out. New aerial images of the structures, which generally measure more than 1,300 feet in diameter, have been taken by David Kennedy of the Aerial Archaeology in Jordan Project and the Aerial Photographic Archive for Archaeology in the Middle East (APAAME), located at the University of Western Australia. “Most are crude circles, but many are clearly intended to be geometrically precise, although often slightly distorted,” he told the Daily Mail. Kennedy hopes the photographs will bring attention to the rings. Excavation could tell scientists more about their construction and purpose.
