Blarney Castle was built nearly six hundred years ago by one of Ireland’s greatest chieftains, Cormac MacCarthy, and has been attracting visitors from all over the world ever since. Over the last few hundred years, millions have flocked to Blarney, making it a world landmark and one of Ireland’s greatest treasures. And notwithstanding how impressive an example it is of a medieval castle, this is probably because of the famous stone you will there at the top of the tower. People from all over the world have climbed up there to kiss it in the hope of acquiring the gift of the gab. Which needless to say they duly receive.
