Brogar Henge and Stone Circle
Stromness, Orkney
associated engineer
date  not known
UK era  Pre-Roman  |  category  Monument, historical  |  reference  HY294134
On a neck of land between the Loch of Stenness and the Loch of Harray stand the remaining 36 stones of the Ring of Brodgar.
There were 60 stones in the original circle. Those that remain are sandstone slabs, of which 27 of the 36 are still upright. They range in height from 2m to 4.5m.
The ring stands on a henge, 113m in diameter and surrounded by a ditch. This was originally cut to a depth of 3m with a width of up to 9m. Material from the cut may have been made to form a bank on the outer lip, although no trace of this remains.
The henge is classified as Class II, having two facing entrances formed by causeways through the surrounding ditch to the north-west and south-east.
It is thought that the land on which the Ring is built was once a promontory jutting into a single, larger loch, which has since receded to become two separate bodies of water.
