The megalithic Kempock Stone, popularly known as Granny Kempock, stands on a cliff behind Kempock Street, the main shopping street in Gourock, Scotland. The stone, or menhir, is grey mica schist and of indeterminate origin, but it has been suggested that it is an old altar to the pagan god Baal, or a memorial to an ancient battle. Supposedly there is a superstition that for sailors going on a long voyage or a couple about to be married, walking seven times around the stone would ensure good fortune. A flight of steps winds up to the stone from Kempock Street below.
