The first complete 3D laser
scan of Stonehenge has been commissioned by English Heritage. The scan has revealed an enormous amount of
data, which is now invisible to the naked eye.
Scott McCracken, the tutor
for the course "The Age of Stonehenge" commented:
A recent
English Heritage project which scanned Stonehenge using laser technology
revealed that the stones were shaped in different ways. The sarsens in the
outer circle to the northeast were worked to make them glisten in sunlight,
perhaps to highlight the view when approaching the circle at the time of a
solstice; by contrast the stones in the southwest area of the circle were not
so worked. This differential working has been taken as proof that the intention
of the builders was to emphasise the alignment of the solstices and in
particular that along the processional way, the Avenue, leading to the monument
from the northeast.
