Certainly one of the most recognisable structures in the world. Over the times I have visited Paris, I've never been inclined to go up. Might lessen its charm. And I just read that in 2007, an American lady (Erika Eiffel) "married" the Eiffel Tower in what is called a commitment ceremony. Erika is part of a organisation that build intimate relationships with objects (basically inanimate things). There is a term for this - objectophile.
