The standing stones known as the Ring of Brodgar is on the West Mainland of the island of Orkney on a narrow strip of land between Loch of Harray and Loch of Stenness. They were erected in the Neolithic period around 5000 years ago, before Stonehenge, and about the same time as the Egyptian pyramids. The stones are fairly local, probably from about 10 miles from the site. There were originally around 60 stones, of which only 27 now remain standing.
