Eiffel Tower, Paris, France

The Eiffel Tower, in French called Tour Eiffel, is a 19th century iron lattice tower located on the Champ de Mars in Paris that has become both a global icon of France and one of the most recognizable structures in the world. The Eiffel Tower, which is the tallest building in Paris,is the single most visited paid monument in the world; millions of people ascend it every year. Named after its designer, engineer Gustave Eiffel, the tower was built as the entrance arch for the 1889 World's Fair.

The tower is massive; it stands 324 m (1,063 ft) tall, about the same height as an 81-story building. It was the tallest structure in the world from its completion until 1930, when it was eclipsed by the Chrysler Building in New York City. Not including broadcast antennas, it is the second-tallest structure in France, behind the Millau Viaduct, just completed in 2004. And while the Eiffel Tower is a steel structure, and weighs approximately 10,000 tonnes, it actually has a relatively low density, weighing less than would a cylinder of air occupying the same dimensions as the tower.

The structure was built between 1887 and 1889 as the entrance arch for the Exposition Universelle, a World's Fair marking the centennial celebration of the French Revolution. Eiffel originally planned to build the tower in Barcelona, for the Universal Exposition of 1888, but those responsible at the Barcelona city hall thought it was a strange and expensive construction, which did not fit into the design of the city. After the refusal of the Consistory of Barcelona, Eiffel submitted his draft to those responsible for the Universal Exhibition in Paris, where he would build his tower a year later, in 1889. The tower was inaugurated on 31 March 1889, and opened on 6 May. Three hundred workers joined together 18,038 pieces of puddled iron (a very pure form of structural iron), using two and a half million rivets, in a structural design by Maurice Koechlin. The risk of accident was great, for unlike modern skyscrapers the tower is an open frame without any intermediate floors except the two platforms. However, because Eiffel took safety precautions, including the use of movable stagings, guard-rails and screens, only one man died.

The tower has three levels for visitors. Tickets can be purchased to ascend either on stairs or lifts to the first and second levels. The walk to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is only accessible by lift. Both the first and second levels feature restaurants.

More than 200,000,000 people 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. The tower has become the most prominent symbol of both Paris and France. The tower is a featured part of the backdrop in literally scores of movies that take place in Paris. Its iconic status is so established that it even serves as a symbol for the entire nation of France, such as when it was used as the logo for the French bid to host the 1992 Summer Olympics.
