Birnam

Birnam, a village between Perth and Dunkeld in E. Perthshire, Scotland. Duncan's Camp is shown on a neighbouring hill, and it was hence, according to the legend adopted by Shakespeare, that his soldiers marched against Macbeth with boughs in their hands, and so fulfilled the prophecy - "Macbeth shall never vanquished be until Great Birnam Wood to high Dunsinane Hill shall come against him."
