Archaeologists have discovered a huge 1.2-mile-wide ring of Neolithic shafts near Stonehenge in southern England. Experts led by the U.K.’s University of Bradford report that the shafts are up to 32.8 feet wide and 16.4 feet deep. The structures have been carbon-dated to 2500 B.C. Up to 20 shafts have been identified, but archaeologists think that, originally, there may have been more than 30.
