The Eiffel Tower

The Eiffel Tower is an iron tower built on the Champ de Mars beside the Seine River in Paris. The tower has become a global icon of France and is one of the most recognizable structures in the world. Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris. More than 200,000,000 have visited the tower since its construction in 1889, including 6,719,200 in 2006, making it the most visited paid monument in the world. Including the 79 ft antenna, the structure is 1,063 ft high (since 2000), which is equivalent to about 81 levels in a conventional building. When the tower was completed in 1889 it was the world's tallest tower — a title it retained until 1930 when New York City's Chrysler Building (1,047 ft tall) was completed. The tower is now the fifth-tallest structure in France and the tallest structure in Paris, with the second-tallest being the Tour Montparnasse (89 ft), although that will soon be surpassed by Tour AXA (738.36 ft). At the time the tower was built many people were shocked by its daring shape. Eiffel was criticised for the design and accused of trying to create something artistic, or inartistic according to the viewer, without regard to engineering. Eiffel and his engineers, as renowned bridge builders however, understood the importance of wind forces and knew that if they were going to build the tallest structure in the world they had to be certain it would withstand the wind.
