Eiffel Tower. A wrought-iron lattice tower on the Champ de Mars in Paris, it is one of the most recognizable structures in the world. Named for its engineer, Gustave Eiffel, the tower was constructed as the centerpiece of the 1889 World's Fair and was initially criticized by some of France's leading artists and intellectuals. Despite this controversial beginning, it has become a global cultural icon of France and one of the most visited monuments with an entrance fee globally.

History

The tower was conceived as the entrance arch for the Exposition Universelle (1889), a world's fair celebrating the centennial of the French Revolution. Its design was selected from proposals submitted by Maurice Koechlin and Émile Nouguier, two senior engineers working for Compagnie des Établissements Eiffel. A petition dubbed "Protest against the Tower of Monsieur Eiffel," signed by figures including Guy de Maupassant and Charles Gounod, decried its construction as a useless monstrosity. Upon completion, it served as a pivotal exhibit hall and radio transmission station, notably aiding Allied forces during the Battle of the Marne in World War I. Its planned demolition after 20 years was averted by its value for radiotelegraphy, and it later survived proposals for dismantling during the German occupation of France.

Design and construction

The initial design was refined by architect Stephen Sauvestre, who added the decorative arches and glass pavilions. Gustave Eiffel personally financed over 80% of the construction costs, securing a 20-year operating permit from the City of Paris. Construction, managed by site director Jean Compagnon, began in January 1887 using over 18,000 prefabricated iron pieces from the Eiffel et Cie factory in Levallois-Perret. The project employed around 300 workers and utilized innovative techniques, such as hydraulic jacks and carefully placed sandboxes, to ensure the precise alignment of the four immense piers. The structure was completed in a record 2 years, 2 months, and 5 days, with no fatal accidents during its assembly, a remarkable feat for the era.

Structure and dimensions

The tower is a masterpiece of structural engineering, standing 330 meters tall including its broadcast antennas. It is composed of over 7,300 tonnes of puddled iron arranged in a distinctive lattice structure, offering minimal wind resistance. The base is formed by four arched legs set in massive concrete foundations, which converge at the first of three public levels. Its height allowed it to hold the title of world's tallest man-made structure for 41 years, until the completion of the Chrysler Building in New York City. The structure sways slightly in the wind and expands in the heat, with its summit moving up to 18 centimeters.

Tourism and cultural impact

Since its opening, the tower has attracted over 300 million visitors, with nearly 7 million annually prior to the COVID-19 pandemic. It has been featured in countless films, from Alfred Hitchcock's The Man Who Knew Too Much to contemporary blockbusters, and has inspired replicas like the Tokyo Tower in Japan. It serves as a backdrop for major events, including the annual Bastille Day military parade and the final stage of the Tour de France. The tower's lighting displays, particularly the sparkling beacon designed by Pierre Bideau, have become a nightly spectacle, and its image is ubiquitously used in global media and advertising to symbolize Paris and French artistry.

Maintenance and operations

The tower is owned by the City of Paris and managed by the Société d'Exploitation de la Tour Eiffel (SETE). A continuous program of maintenance involves repainting the entire structure every seven years, a process requiring 60 tonnes of paint and performed by specialized alpinists. Major renovations have periodically upgraded its facilities, such as the installation of glass floors and energy-efficient lighting systems. It houses two renowned restaurants, Le Jules Verne and the Madame Brasserie, and several broadcast antennas used by major French television and radio stations, including Radio France and TDF Group. Strict security protocols, managed in coordination with the Préfecture de Police, are in place to protect the monument and its visitors.
