There are many great views of the tower from many parts of
the City as you would guess, as well as some great views
from the tower itself.
This is a view looking straight up at what's supposed to be
a guy working on the tower in typical garb. It's a mannequin
dressed in a jumpsuit and equipped with all the necessary
tower-climbing gear.
Looking southwest from the second highest deck on the tower
at the River Seine.
Looking due east the Rive Seine splits the upper half of
this image.
Turning a bit toward the south you can see the Dome at
Invalides.
And a bit more toward the south (actually due
southeast if there is such a thing) is a view of the Champs
du Mars with the Tour Montparnasse in the background, the
tallest building in all of France.
