23 Dec 2009, Salisbury, Wiltshire, England, UK --- Stonehenge. This ancient arrangement of large standing stones (megaliths) on Salisbury Plain, England, is thought to have been built around 2000 BC by neolithic peoples. Some of the stones are thought to form markers that indicate rising and setting points for the Sun and the Moon, allowing accurate prediction of forthcoming lunar and solar eclipses. --- Image by © David Nunuk/Science Photo Library/Corbis
