The tower is the tallest building in Paris, and the most-visited paid monument in the world; more than 7 million people ascended it in 2011. The tower received its 250 millionth visitor in 2010.
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. Today, it is the second-tallest structure in France, after the Millau Viaduct.
In 2014, the Eiffel Tower underwent a €30 million refit, that has modernised the pavilions on the first floor, introduced access to the outer platform with its spectacular panoramic views of the city to those in wheelchairs. A cinema room shows historic and recent film of the tower.
The project aimed to reduce the tower's carbon footprint by repositioning glass panels to reduce air-conditioning costs in summer, introducing solar panels, installing a rainwater collection system, and using LED lighting.
The renovated floor, however, has a new attraction that is not for the faint-hearted or those with vertigo. Visitors can now stand on a glass floor and see straight down to the ground from a height of 57 metres, rather as they now can on the Aiguille du Midi above Chamonix, although in Chamonix the drop is rather greater.
