The Eiffel Tower is a wrought-iron lattice tower on the Champ de Mars in Paris, France, which was named after Gustave Eiffel, whose company built the building. It started as the entrance to the 1889 World’s Fair and was criticized by some of France’s leading artists. But has developed into one of the most popular cultural icons and recognizable structures in the world.

It is the second tallest free-standing building in France, after the Millau Viaduct. The Eiffel Tower is 324 meter tall 125 meters on each side. It has surpassed the Washington Monument, and is as tall as an 81-story building. It is also the most paid- visited monument in the world, as of 2015, 6.91 million people ascended the structure.
