Ireland's folklore is deep—Finn McCool, the Children of Lir, the Banshee, Tír na nÓg—but the legend that draws 400,000 visitors a year to a castle battlement in County Cork is the Blarney Stone.
Set into the battlements of 15th-century Blarney Castle, the stone supposedly grants "the gift of gab"—eloquence, persuasiveness, the ability to flatter without seeming to—to anyone who kisses it.
You lie on your back, lean backward over the parapet (assisted by staff), grip iron rails, and kiss the underside of the stone—head tilted upside down, 85 feet above ground. Safety rails added in modern times; before, it was held by ankles.
Winston Churchill, Mick Jagger, Laurel & Hardy, John F. Kennedy (as senator), Ronald Reagan, Billy Connolly, millions of tourists. No scientific evidence of eloquence transfer exists. The placebo effect is powerful.
Blarney Castle grounds also feature the Poison Garden, Rock Close (druidic site), and Blarney House (19th c. mansion). The stone is the hook; the place is the reward.
