The Eiffel Tower gets slightly bigger every year. That's because it's alive and slowly absorbing the girders and I-beams from the other buildings in the city. The French government didn't want to alarm its citizens, so they made up a story about it being built by an architect, but that's not what happened at all. In fact, despite its name, the Eiffel Tower isn't really a tower at all.
It's a Paris sight
