The Eiffel Tower (La Tour Eiffel) is a wrought-iron lattice tower on the Champ de Mars in Paris, standing 330 meters tall including its antenna. Designed by Gustave Eiffel's engineering company and built between 1887 and 1889 as the centerpiece of the 1889 Exposition Universelle (World's Fair), it was initially met with fierce criticism from prominent Parisian artists and intellectuals who called it an eyesore.
Introduction
Today the Eiffel Tower is universally recognized as one of the most iconic structures ever built. It attracts nearly 7 million visitors annually, making it the most visited paid monument in the world. The tower served as the world's tallest man-made structure for 41 years until the completion of the Chrysler Building in New York in 1930, and it remains the tallest structure in Paris.
Architecture & Engineering
- Designer: Gustave Eiffel (Maurice Koechlin & Emile Nouguier, engineers)
- Height: 330 m (with antenna); 300 m (structural)
- Weight: 7,300 tonnes of iron
- Rivets: 2.5 million
The Eiffel Tower is composed of 18,038 pieces of puddled iron connected by 2.5 million rivets. The entire structure was prefabricated in Eiffel's factory on the outskirts of Paris, with each piece manufactured to tolerances of a tenth of a millimeter. On-site assembly took just over two years, an extraordinary feat for the era, with no worker fatalities during construction.
The tower's lattice design was not merely decorative but was the result of advanced mathematical calculations to minimize wind resistance. Eiffel and his engineers used graphical methods to determine the optimal curvature of the tower's legs, ensuring that the tangent at any point along the curve would intersect with the resultant of the forces of wind and gravity acting above that point. This elegant engineering solution gives the tower its distinctive exponential profile.
History & Construction
- Construction Period: January 1887 – March 1889
- Cost: 7.8 million francs (about $40 million today)
- Original Permit: 20-year demolition clause
- Saved By: Its usefulness as a radio transmission tower
Construction began in January 1887 with the excavation of the foundations, which extend to a depth of 15 meters on the side nearest the Seine. The tower was assembled in just 26 months using an innovative system of hydraulic jacks and temporary wooden scaffolding. At its peak, about 300 workers were on site simultaneously, and the project was completed on time and within budget.
The tower was originally granted a 20-year permit, after which it was scheduled for demolition in 1909. Gustave Eiffel, anticipating this fate, promoted the tower's use for scientific experiments, particularly in wireless telegraphy. By 1910, the tower had become an indispensable radio antenna, transmitting signals that were critical to French military communications during World War I, which ensured its permanent survival.
Cultural Significance
- Annual Visitors: Nearly 7 million
- Cultural Status: UNESCO World Heritage Site (part of Paris, Banks of the Seine)
- Nickname: La Dame de Fer (The Iron Lady)
The Eiffel Tower has become not just a symbol of Paris but of France itself, and arguably the single most recognizable man-made structure on Earth. It has appeared in thousands of films, paintings, and photographs, and its silhouette is reproduced on countless souvenirs and commercial products worldwide.
The tower has also served as a canvas for artistic expression: it has been illuminated in countless color schemes to mark occasions from New Year's Eve to international solidarity events. In 2024, the tower was repainted in a golden-brown shade specifically chosen for the Paris Olympics, a process that required 60 tonnes of paint and took three years to complete.
Visitor Experience
- Three Levels: 1st floor (57 m), 2nd floor (115 m), summit (276 m)
- Glass Floor: 1st floor transparent walkway
- Restaurants: Le Jules Verne (Michelin-starred) on 2nd floor
Visitors can ascend the tower by elevator or by climbing the 674 steps to the second floor. The first floor features a glass floor section that allows visitors to look straight down to the ground 57 meters below, as well as exhibition spaces detailing the tower's history. The second floor offers panoramic views of Paris and houses the Michelin-starred restaurant Le Jules Verne.
The summit, accessible only by elevator from the second floor, provides views extending up to 72 kilometers on a clear day. A reconstructed version of Gustave Eiffel's private office, complete with wax figures of Eiffel and Thomas Edison, can be seen at the top. The tower's 20,000 light bulbs create a sparkling display for five minutes every hour after dark, a spectacle visible from across Paris.
Key Facts
- The Eiffel Tower was built in just 26 months for the 1889 World's Fair
- It stands 330 meters tall and weighs 7,300 tonnes of puddled iron
- Nearly 7 million people visit annually, making it the world's most visited paid monument
- The tower was saved from demolition by its usefulness as a radio transmission tower
- It was the world's tallest structure for 41 years until 1930
Fun Facts
- The tower grows up to 15 cm taller in summer due to thermal expansion of the iron
- Gustave Eiffel had a private apartment at the summit where he entertained guests including Thomas Edison
- The tower has been sold by con artists at least twice — Victor Lustig famously sold it as scrap metal in 1925
- It takes 60 tonnes of paint to repaint the tower, a process done every 7 years
Final Thoughts
The Eiffel Tower stands as perhaps the greatest testament to the power of engineering and vision to create something that transcends its original purpose. Built as a temporary exhibition piece and reviled by many at its debut, it has become the most beloved and recognizable landmark on Earth — proof that true genius often goes unrecognized in its own time.
