The Ring of Brodgar is both an enigmatic historical attraction and an area of spectacular natural beauty.

Examine the UNESCO-listed site, which sits amid the rolling hills and tranquil lochs of the Orkney Mainland.
Much of the history of this landmark remains a mystery, such as why and how it was constructed. Historians believe that the site probably dates from between 2500 and 2000 B.C. and would once have contained about 60 different stones. Try to guess the purpose of the monument popular theories suggest it could be a prehistoric observatory or a place of pagan worship.
Rangers from Historic Scotland lead guided tours around the site throughout the summer. Put on a pair of sturdy boots and join them. Explore the Ring of Brodgar and venture across to the Stones of Stenness, diverting to enjoy the wildlife at the nature reserve. Otters, wildfowl, skylarks and hares populate the protected countryside around the circle.
Several burial mounds lie next to the Ring of Brodgar. Head toward Loch Stenness to find Fresh Knowe and Plumcake Knowe, two of the larger archaeological sites, which were excavated in the mid-19th century.
