Tony sans Cookie: As an intersting aside, in Father Peter O'Leary's autobiography "Mo Sgeal Fein" in one chapter entitled "Tri Liathroidi Dubha" (Three Black Balls) he describes as as young school boy seeing what appeared to him to be three slender poles with three black balls on top of them on the top of Macroom Castle. He later found out that they were iron spikes holding the skulls of three executed men.
