Pedras de abalar

The Pedras de abalar, Galician for "oscillating stones", are several large stones in Galicia, Spain, that can easily be moved by a person or the wind. One of these is in Muxía, and is known as the "Pedra da Barca". These are large stones that are balanced on a point, so that they can be moved back and forth easily, or even wiggle in response to the wind. These were used at one time to determine the guilt or innocence of those accused of serious crimes. In English, such stones have been called rocking stones, or logan stones.

The stone by the Our Lady of the Boat shrine in Muxía, A Coruña.
