La Défense is a business district West of Paris were are located most of the
high buildings. It is in the exact alignment of the "historical axis" starting
at the Louvre museum and going to the Concorde Obelisk and the Arch of Triumph.

To close this perspective, the Grande Arche was build in the '90.

Looking like a hollowed cube, it can be visited. The top level hosts
exhibitions. When I visited yesterdays there was a "computer museum" (with some
machines I've used 20 years ago!) and an anaglyph exposition (drawing made with
computer, nice but not tremendous and the author has chosen red-green glasses
but with the red lens over the RIGHT eye).

You also have a nice view towards Paris from a lookout. The Arch of Triumph can
be seen in the distance as well as the Eiffel Tower (not easily recognizable as
it is in the same alignment as the Maine-Montparnasse tower.
I used to work in the black Areva tower. My office was at the 42th level, at the
closest corner in the picture and the view was splendid, better that the one
from the top of the Grande Arche!
I've taken five pictures increasing the stereo base, here it should be about 5-7
m.
