The Lochmaben Stone (grid reference NY 3123 6600) is a megalith standing in a field, nearly a mile west of the Sark mouth on the Solway Firth, three hundred yards or so above high water mark on the farm of Old Graitney in Dumfries & Galloway in Scotland. The area is also known as Stormont. Together with a smaller stone it is all that is left of a stone circle dating back to around 3000BC.
