Everything you always wanted to know about the Eiffel Tower! This incredible monument that became the symbol of a city, Paris, and of a country, France, has a fascinating history. The Eiffel Tower is an iron lattice tower located on the Champ de Mars in Paris, France. It was named after the engineer Alexandre Gustave Eiffel, whose company designed and built the tower. Erected in 1889 as the entrance arch to the 1889 World's Fair, it was initially criticized by some of France's leading artists and intellectuals for its design, but has become both a global cultural icon of France and one of the most recognisable structures in the world. The tower is the tallest structure in Paris and the most-visited paid monument in the world; about 7 million people ascended it in 2014. The tower received its 250 millionth visitor in 2010.
