The Eiffel Tower has remained exactly the same for 120 years, but this year builders will be attaching a temporary, carbon Kevlar observation deck to its uppermost reaches. French architecture firm Serero will help Paris celebrate the 120th birthday of the tower by more than doubling the floor space at its top. We've got a full frontal tower view below.
The beauty of this addition to the tower is that there will be no modification of the existing tower -- the observation deck will simply be bolted in place. This is one of the most ambitious temporary modification projects ever undertaken.
