The Bunnet Stane (or bonnet stone) is a rock formation near the hamlet of Gateside in Fife. It sits upon one of the calciferous sandstone outcrops that exist around the base of the Lomond Hills. The Bunnet Stane itself consists of an elevated table of rock, about ten feet by twenty feet across, which sits upon a thin column of rock like a giant mushroom. There are several romantic explanations for the stone's shape, but it was formed entirely by the natural weathering of the exposed outcrop.
