The Eiffel Tower ( EYE-f?l; French: tour Eiffel [tu???f?l] (listen)) is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It's named after the engineer Gustave Eiffel, whose firm designed and built the tower.
Constructed from 1887 to 1889 as the entrance to the 1889 World's Fair, it was initially criticised by a number of France's leading artists and intellectuals for its design, but it has become a worldwide cultural icon of France and one of the most recognisable structures on the planet. The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015.
The tower is 324 metres (1,063 ft) tall, about the same height as an 81-storey construction, and also the tallest structure in Paris. Its base is square, measuring 125 metres (410 ft) on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City was completed in 1930.
