Standing Stones of Stenness

Part of this Mainland area's concentration of neolithic monuments, four mighty stones remain of what was once a circle of 12. Recent research suggests they were perhaps erected as long ago as 3300 BC, and they impose by their sheer size; the tallest measures 5.7m in height. The narrow strip of land they're on, the Ness of Brodgar, separates the Harray and Stenness lochs and was the site of a large settlement inhabited throughout the neolithic period (3500–1800 BC).
