The Ring of Brodgar, on Orkney, is about 340 feet in diameter. It was originally composed of some 60 evenly-spaced stones, but now 36 stones or stumps of stones remain.

An impressive ditch, up to ten feet deep,was cut into the bedrock just outside the stones; the ditch is broken by two causeways, at the north-west and the south-east.

One of the stones has been graffittied with Norse runes (much like the tomb of Maeshowe).

Brodgar lies in an area incredibly rich in archaeology between the Stones of Stenness to the south and the Ring of Bookan to the north.
