Eiffel Tower
The Eiffel Tower is to Paris what the Statue of Liberty is to New York and what Big Ben is to London: the ultimate civic emblem. French engineer Gustave Eiffel spent two years working to erect this iconic monument for the World Exhibition of 1889. Because its colossal bulk exudes such a feeling of permanence, it's hard to believe that the tower nearly became 7,000 tons of scrap when the concession expired in 1909. Only its potential use as a radio antenna saved the day. Though many prominent Parisians derided it at first, the tower gradually became part of the city's topography. It's most breathtaking at night, when every girder is highlighted in a glittering show of 20,000 golden lights for five minutes every hour on the hour from nightfall until midnight (until 1 am in summer).
More recent enhancements include a renovation of the first level that added a vertigo-inducing "transparent" floor 187 feet above the esplanade as well as a miniturbine plant, four vertical turbine windmills, and eco-friendly solar panels to minimize the tower's carbon footprint over time. You can stride up 704 steps as far as the second level, but only the elevator goes to the top. The view of the flat sweep of Paris at 1,000 feet is sublime—especially if you come in the late evening, after the crowds have dispersed. Beat the crushing lines by reserving your ticket online, or book a skip-the-line guided tour offered by many companies (from €47). Better yet, ride up the private elevator to chef Frédérick Anton's Jules Verne restaurant—with its Michelin star—on the tower's second floor. It's about as dramatic a lunch or dinner spot as you'll find, apart from Madame Brasserie, a chic sit-down bistro helmed by Michelin-starred chef Thierry Marx on the first floor (online reservations for both restaurants are a must). Or you can watch the glimmering lights from the top of the tower over a glass of bubbly or a nonalcoholic drink at the Bar à Champagne. There are also small "buffet" snack shops on the esplanade and the first and second floors.
At the tower's tippy top is Gustave Eiffel's "secret apartment," which he used as his office, including wax mannequins of Eiffel in conversation with Thomas Edison; the blonde woman in the background represents Claire, Eiffel's oldest daughter, with whom he was very close. You'll also hear actual recordings of Eiffel's voice.
