In section it is sub-rectangular, with a minimum thickness of , rising to a tapered top about high. Excavation has shown that a further is buried in the ground. It is from the centre of Stonehenge circle. It leans towards the southwest nearly 27 degrees from the vertical. The stone has an overall girth of and weighs about 35 tons. It is surrounded by the Heelstone Ditch. Myths and legends of the Devil  striking a "Friar's Heel" with a stone resulted in its eccentric name, "Heel Stone". Some claim "Friar's Heel" is a corruption of "Freyja's He-ol" or "Freyja Sul", from the Nordic goddess Freyja and (allegedly) the Welsh words for "way" and "Sunday" respectively. It is doubtful whether any prehistoric standing stone has experienced as many name changes and interpretations. Only in the past three decades have scientists used the name "Heel Stone" consistently.
