Interesting Facts and Secrets About the Eiffel Tower

Few monuments in the world are as iconic as the Eiffel Tower. Rising above Paris, it is more than just a steel structure—it is a symbol of French art, engineering, and romance. Millions of visitors travel to Paris each year to witness its beauty, making it one of the most visited paid monuments in the world.
Yet, behind its stunning iron framework lies a fascinating story filled with history, controversies, and secrets that many people don’t know. From its construction challenges to its role in history, the Eiffel Tower has witnessed incredible transformations since it first appeared in 1889.
Let’s explore the most interesting facts and secrets about the Eiffel Tower that will deepen your appreciation of this global landmark.
The Historical Background of the Eiffel Tower
The Eiffel Tower was constructed for the 1889 Exposition Universelle (World’s Fair) held in Paris, to celebrate the 100th anniversary of the French Revolution. Designed by Gustave Eiffel’s engineering company, the tower was initially met with criticism. Many artists and intellectuals in Paris called it an “eyesore” and a “monstrosity of iron.”
Despite the backlash, Gustave Eiffel pushed forward. He envisioned the tower as a showcase of French innovation and industrial strength. Built in just over two years (1887–1889), it stood as the tallest structure in the world until 1930, when New York’s Chrysler Building surpassed it.
Over time, what was once called “ugly” became a universal symbol of Paris. Today, the Eiffel Tower attracts over 7 million visitors annually, making it one of the most recognized landmarks across the globe.
1. The Eiffel Tower Was Not Designed to Be Permanent
When Gustave Eiffel proposed the structure, it was supposed to stand for only 20 years. After the World’s Fair, the plan was to dismantle it.
However, its usefulness as a radio transmission tower saved it from demolition. By the early 20th century, the French military and government realized its strategic importance for communication, particularly during World War I. Without its role in advancing wireless telegraphy, the Eiffel Tower might not exist today.
2. It Took Over 18,000 Iron Pieces to Build
The Eiffel Tower is a masterpiece of engineering. Construction required more than 18,000 prefabricated iron parts, held together by 2.5 million rivets. At its completion in 1889, it weighed around 10,000 tons.
Despite the scale of the project, the assembly process was carefully organized. Workers relied on cranes mounted on the structure itself to lift heavy pieces into place—a revolutionary technique at the time. This efficiency allowed construction to finish ahead of schedule, just in time for the World’s Fair.
3. It Was the Tallest Structure in the World for 41 Years
Standing at 300 meters (984 feet) upon completion, the Eiffel Tower held the record as the world’s tallest structure for over four decades. It wasn’t until 1930, when the Chrysler Building in New York City was completed, that the record was broken.
Today, with modern broadcasting antennas added, the tower measures about 330 meters (1,083 feet) tall. While skyscrapers have overtaken it in height, its elegance and historical significance remain unmatched.
4. Parisians Once Hated It
When the Eiffel Tower was unveiled, many Parisians were furious. Writers, painters, and architects signed a petition calling it “useless and monstrous.” Even the famous French novelist Guy de Maupassant reportedly despised the structure, though he was often seen dining in its restaurant because it was the only place in Paris where he couldn’t see it.
Ironically, what was once considered an “eyesore” is now one of the most beloved symbols of French pride and culture.
5. It Changes Color Regularly
The Eiffel Tower is repainted every seven years to protect it from rust and weather damage. Surprisingly, it has not always been the bronze-brown color we know today.
- In the late 19th century, it was painted red-brown.
- Later, it shifted to yellow-ochre.
- Finally, in 1968, it was coated in the famous “Eiffel Tower Brown”, a custom shade designed to complement the Parisian skyline.
It takes about 60 tons of paint and months of work to complete each repainting cycle.
6. Gustave Eiffel Had a Secret Apartment Inside
At the very top of the Eiffel Tower, Gustave Eiffel built a private apartment for himself. This cozy space was furnished with wooden cabinets, velvet sofas, and even scientific equipment.
While he occasionally used it to entertain guests like Thomas Edison, the apartment mostly served as a retreat for quiet reflection. Today, visitors can peek into this hidden apartment, which remains preserved as it was during Eiffel’s time.
7. It Played a Role in World Wars
The Eiffel Tower has more than just artistic significance; it also has military history. During World War I, the tower’s radio transmitters were used to jam German communications, playing a crucial role in the French war effort.
Later, during World War II, when Nazi forces occupied Paris, Hitler ordered the tower to be destroyed. Thankfully, the command was never carried out. However, French resistance fighters famously cut the tower’s elevator cables so that German soldiers had to climb its 1,665 steps to hoist their flag.
8. It Expands and Contracts with the Weather
The Eiffel Tower is not a static structure. Due to its iron composition, it expands in heat and contracts in cold weather. On hot summer days, it can grow by about 15 centimeters (6 inches).
This natural expansion doesn’t affect its stability, as engineers designed it with such variations in mind.
9. Millions of Lights Illuminate It Every Night
One of the most magical aspects of the Eiffel Tower is its nightly light show. Since 1985, the tower has been fitted with thousands of sparkling bulbs that flash for five minutes every hour after sunset.
Additionally, powerful golden lights highlight the tower’s silhouette, making it visible across Paris. The illumination requires about 20,000 bulbs and has become one of the city’s most famous attractions.
10. The Eiffel Tower Is an Economic Powerhouse
Far from being just a tourist attraction, the Eiffel Tower contributes significantly to the French economy. Studies estimate its brand value at over €400 billion, making it one of the most valuable monuments in the world.
Ticket sales, restaurants, gift shops, and guided tours generate millions of euros annually. With more than 7 million visitors per year, it remains one of the top-earning monuments globally.
11. It Inspired Global Replicas
The Eiffel Tower’s unique design has inspired replicas around the world. You can find Eiffel Tower-inspired structures in Las Vegas (USA), Tokyo (Japan), Shenzhen (China), and Lahore (Pakistan).
Although none match the original in scale or grandeur, they highlight the universal appeal of Gustave Eiffel’s masterpiece.
12. Strange Stunts and Events Have Taken Place
The Eiffel Tower has seen its share of daring acts. Adventurers have parachuted, bungee jumped, and even attempted to cycle down its steps.
One bizarre event occurred in 1912, when Franz Reichelt, a tailor, tested his homemade parachute by jumping from the first deck. Sadly, the stunt ended in tragedy. Despite this, the tower continues to be a site for festivals, fireworks, and cultural events.
13. It Symbolizes Love and Romance
Today, the Eiffel Tower is a global icon of romance. Thousands of marriage proposals take place here every year, and it remains a favorite destination for honeymooners. Its elegant design and Parisian setting make it the ultimate symbol of love.
