"Bluestonehenge" or "Bluehenge" is a prehistoric henge and stone circle monument that was discovered by the Stonehenge Riverside Project about 1 mile (1.6 km) south-east of Stonehenge in Wiltshire, England. All that presently remains of the site is the ditch of the henge and a series of stone settings, none of which is visible above ground.
