PERTHSHIRE ROCK ART SHEDS LIGHT ON SCOTLAND'S PAST

A team working on National Trust for Scotland (NTS) land as part of the Ben Lawers Historic Landscape Project found the previously undiscovered ‘cup-and-ring’ style markings on a hillside overlooking Loch Tay and Kenmore. The carvings could date back to Neolithic times and be up to 5,000 years old.
