A large upright stone, standing where the Avenue meets the earthwork enclosure.
This stone, unlike all the other sarsen stones at Stonehenge, is unworked and retains its natural shape. It may have been an isolated stone that was raised upright in the Neolithic period. It marks the position of the rising sun at the summer solstice. It may always stood alone or have been paired originally with a second, now lost, stone. Its name may derive from a legend associated with Stonehenge that relates how the Devil threw a stone at a friar, leaving the friar's heel imprint on it.
