The Eiffel Tower stands on the Champ de Mars in Paris, France. Built by Gustave Eiffel's company from 1887 to 1889 as the centrepiece of the 1889 World's Fair, it is the tallest structure in Paris and the city's best-known symbol, known locally as 'La dame de fer', the Iron Lady.
Why it is worth the trip
Walk the length of the Champ de Mars first: the tower shifts from engineering to skyline with every step. Three levels await, from a transparent floor on the first to the highest public observation deck in the European Union at 276 m on the top, where Gustave Eiffel's small private apartment opened to public viewing in 2015. Knowing the history sharpens the view: a petition against the tower ran in Le Temps on 14 February 1887, and during the First World War a military radio centre here intercepted enemy messages. Stay for nightfall, when 20,000 light bulbs illuminate it.
The best time to go
Go early: arrive at least 30 minutes before opening time, since the tower is one of Paris's choke points and waits of an hour or more are normal. Winter brings thinner crowds and, from mid-December to the end of January, an ice rink on the first floor. Whatever the season, stay until dark for the nightly illumination.
How long to allow
Allow a substantial part of a day; the site rewards unhurried time, and queues add to it. Pair the visit with a walk through the Champ de Mars.
Getting there
The tower sits on the Champ de Mars, with the Seine at its feet. Walk the full length of the park before ascending.
What to book ahead
Start with the tower's own booking page and choose your season. Le Jules Verne on the second level takes reservations two months in advance; the Paris Museum Pass, sold at tourist offices, FNAC branches and main Métro and RER stations, lets you skip lengthy queues at many sights.
Nearby
The Arc de Triomphe and the Champs-Élysées are within reach, and the Louvre Museum and the Musée d'Orsay are further city landmarks.
