Blarney Castle was built nearly six hundred years ago by one of Ireland's greatest chieftains, Cormac MacCarthy, and has been attracting attention beyond Munster 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. Now that might have something to do with the Blarney Stone, the legendary Stone of Eloquence, found at the top of our Tower. Kiss it and you'll never again be lost for words.
