Origin of StonehengeMiddle English stonheng ; from ston, stone + Old English henge, (something) hanging: for Indo-European base see hang
A group of standing stones on Salisbury Plain in southern England. Dating to c. 2200–1800 BC, the megaliths are enclosed by a circular ditch and embankment that may date to c. 3000. The arrangement of the stones suggests that Stonehenge was used as a religious center and also as an astronomical observatory.
