The Eiffel Tower is an iron tower built on the Champ de Mars beside the River Seine in Paris.
On the Eiffel Tower, seventy two names of French scientists, engineers and some other notable people are engraved in recognition of their contributions by Gustave Eiffel.
It's famous because it was never supposed to stay there. Gustave Eiffel designed it for the temporary Exposition Universelle, and a lot of crazy other buildings and constructions were all around the Eiffel Tower during the Exhibition. But it looked so strange and became so popular that they didn't destroy it.
