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.
The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs 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. The third and highest level is accessible only by lift - stairs exist but they are not usually open for public use. Both the first and second levels feature restaurants.
There is a ticket office at the foot of the Tower, open every day, but you can buy tickets online. These electronic tickets - which you can print at home or save to your mobile phone - allows you to go directly to the queue for those with tickets. But be aware, that these tickets are date and time specific.
