|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.
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 stands at 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, 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 a cylinder of air occupying the same dimensions as the tower. 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.
