Dunnottar Castle, an old castle of the Keiths now in ruins, on the flat summit of a precipitous rock 1½ m. S. of Stonehaven, Kincardineshire, Scotland, and connected with the mainland by a neck of land called the “Fiddle Head”; famous in Scottish history as a State prison, and as the place of safe-keeping at a troubled period for the Scottish regalia, now in Edinburgh Castle.
