The buttresses formed a
frame, locking the Sarsen Circle together with tremendous strength and
stability. To connect the buttresses together and make the frames, a
ring of cross members was used. These cross members were directly above
the upright wooden supports, one third of the distance along the
buttresses and measured to be two thirds of the height of the Sarsen
circle.
So where are they now? The stone footings which
once filled the Y-Z holes were removed centuries ago. A farmer told
Bruce that to remove a stone of this size, you light a fire at
one side and the stone will crumble and is then easily removed. One of
the mysteries of the Stonehenge site is that so many of the Y-Z holes
have had fires in them at one side.
