The Watch Stone

The Watch Stone, also spelled Watchstone, is a standing stone or menhir from the Neolithic period, standing between the Loch of Stenness and the Loch of Harray on Mainland, one of Scotland's Orkney Islands. The megalith is part of the Heart of Neolithic Orkney World Heritage Site.
The stone is on the west side of the road. About 170 meters to the south-southeast are the Stones of Stenness. North of the stone lies the Ring of Brodgar.
The Watch Stone is a rectangular stone 5.6 meters high, 1.5 meters wide and 40 centimeters thick. The Watch Stone is the tallest monolith in this area. The base is provided with modern masonry for reinforcement. The front and back of the stone face east and west.

There is a great deal of conjecture about the history of the "Watchstone" (even the name of this standing stone is up for debate). There is little certainty other than it is surely one of Orkney’s most imposing standing stones, and it dominates the south-eastern end of the Brig o’ Brodgar – the place where the Harray and Stenness lochs meet.
