Stone Circles, circles of standing stones (q.v.) found in various parts of Great Britain, North Europe generally, and also, but of more recent origin, in North India; were certainly, in the most of cases, set up to mark the circular boundary of a place of burial; erroneously ascribed to the Druids; from the character of numerous cinerary urns exhumed, seem to have belonged to the bronze age in Great Britain; most interesting are those of Stennis, in Orkney, with a circumference of 340 ft., Avebury, in Wiltshire, and Stonehenge (q.v.).
