Cawdor is a little village surrounded by forest and farmland in the north of Scotland, and Shakespeare had set Macbeth there without bothering to research the fact that the real Macbeths never set foot in the place because they died three hundred years or so before Cawdor Castle was even built. (This lack of attention to historical detail is more grist to the mill for my theory that Shakespeare, if he were alive today, would be writing for TV. But somewhere classy, though.)
