1911 Encyclopædia Britannica/Dunsinane

DUNSINANE, a peak of the Sidlaw Hills, in the parish of Collace, Perthshire, Scotland, 8 m. N.E. of Perth. It is 1012 ft. high, and commands a fine view of the Carse of Gowrie and the valley of the Tay. Its chief claim to mention, however, is due to its association with Birnam Wood (about 12 m. N.W.) in two well-known passages in Shakespeare’s Macbeth. An old fort on the summit, of which faint traces are still discernible, is traditionally called Macbeth’s Castle.
