Stonehenge Model vs Reality.

Click to embiggen - The exhibition at the New Visitor Centre near Stonehenge has some marvelous brass models of the monument through its development and decline.

I found this picture (left) of the model as it is and thought it instructive to compare it with an aerial shot of the monument taken last summer by Adam Stanford 

I note that in the model the Great Trilithon isn't twisted as in so many models.
