     The Eiffel Tower (French: La Tour Eiffel) is an iron lattice tower located on the Champ de Mars in Paris, named after the engineer Gustave Eiffel, whose company designed and built the tower. Erected in 1889 as the entrance arch to the1889 World's Fair , it has become both a global cultural icon of France and one of the most recognizable structures in the world. The tower is the tallest structure in Paris and the most-visited paid monument in the world; 7.1 million people ascended it in 2011. 

The tower stands 320 metres (1,050 ft) tall, about the same height as an 81-storey building. During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930. However, because of the addition, in 1957, of the antenna atop the Eiffel Tower, it is now taller than the Chrysler Building. Not including broadcast antennas, it is the second-tallest structure in France, after the Millau Viaduct.

     The design of the Eiffel Tower was originated by Maurice Koechlin and Emile Nouguier, two senior engineers who worked for the Compagnie des Establissements Eiffel.

     The projected tower had been a subject of some controversy, attracting criticism both from those who did not believe that it was feasible and also from those who objected on artistic grounds. Their objections were an expression of a longstanding debate about relationship between architecture and engineering.

Gustave Eiffel responded to these criticisms by comparing his tower to the Egyptian Pyramids : "My tower will be the tallest edifice ever erected by man. Will it not also be grandiose in its way ? And why would something admirable in Egypt become hideous and ridiculous in Paris ? And going on to point out that the protest was irrelevant since the project had been decided upon months before and was already under construction."

So, some of the protestors were to change their minds when the tower was built: others remained unconvinced.

     Today, the Tower is widely considered to be a striking piece of structural art.
