The tartan piece can be dated to around 1500-1600 A.D., making it the oldest known surviving specimen of true tartan in Scotland.
“The piece of material could be up to 500 years old, according to scientists, who said it survived because of the lack of air that was getting to it. The fabric was found almost 40 years ago in a peat bog — a type of wetland — in the Glen Affric valley, 15 miles west of Loch Ness.”
