Blarney Castle - County Cork, Ireland. Built in 1446 by Dermot McCarthy, King of Munster. McCarthy made promises to deliver his castle to the Crown but he continued to delay in doing so with idle promises, this became known as talking 'Blarney'. At the top of the Castle lies the Blarney Stone. It is called this because as legend says, if you kiss the Blarney Stone, it gives you the gift of eloquence, or the 'Gift of the Gab'.
