The Eiffel Tower (French: La Tour Eiffel, [tuʁ ɛfɛl]) is an iron lattice tower located on the Champ de Mars inParis, named after the engineer Gustave Eiffel, whose company designed and built the tower. Erected in 1889 as the entrance arch to the 1889 World's Fair, it has become both a globalcultural icon of France and one of the most recognizable structures in the world. The tower is thetallest structure in Parisand the most-visited paid monument in the world; 7.1 million people ascended it in 2011. The tower received its 250 millionth visitor in 2010.
The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-floor building. During its construction, the Eiffel Tower surpassed theWashington 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 Citywas built in 1930. Because of the addition of the antenna atop the Eiffel Tower in 1957, it is now taller than the Chrysler Building by 17 feet (5.2 m). Not including broadcast antennas, it is the second-tallest structure in France, after the Millau Viaduct.
The tower has three levels for visitors. The third level observatory's upper platform is at 279.11 m (915.7 ft) the highest accessible to the public in the European Union. Tickets can be purchased to ascend, bystairs or lift (elevator), to the first and second levels. The walk from ground level to the first level is over 300 steps, as is the walk from the first to the second level. Although there are stairs to the third and highest level, these are usually closed to the public and it is usually accessible only by lift. The first and second levels have restaurants.
