21 Fun and Interesting Eiffel Tower Facts

1. The Eiffel Tower Is the Tallest Building in Paris

Standing at 803 meters, or 1,083 feet, tall it is the equivalent of an 81-story building. When it was unveiled during the Paris World's Fair in 1889, it was the tallest building in the world!

2. Its Height Changes

Depending on the season, the Eiffel Tower can be up to seven inches taller or six inches shorter. During hotter months, over 104 degrees Fahrenheit, to be exact, the iron expands and causes the tower to be about seven inches taller. In colder temperatures, the iron contracts and shortens the tower by about six inches.

3. It Was Supposed To Be Demolished

20 years after its assembly, the tower was supposed to be torn down! It was only supposed to be a display of the industrial mastery of France during the World Fair. In order to keep this landmark a part of living history, a radio antenna was placed at the very top. Deemed too important to destroy by city officials, the now-radio-transmission tower was saved from demolition. The addition of this antenna caused the height of the tower to go from 1,024 feet to its current 1,083.

4. The Tower Was Once Yellow

In order to preserve the wrought iron from any natural elements, the tower was once given a coat of yellow paint. However, since 1968 the official color has been "Eiffel Tower Brown" with the top being somewhat darker than the bottom, giving the tower an ombre effect.

5. It Can Only Be Painted by Hand

Speaking of the paint job, this massive structure can only be painted by hand. It takes 50 painters and 60 tons of paint to get the job done, and is performed every seven years. To date, it has been repainted 19 times, most recently being a golden upgrade for the 2024 Olympics.

7. There Are 1,665 Steps

Made of three sections, the Eiffel Tower includes much more than just glittering lights and many steps!

During this daily show, many onlookers revel in its beauty while trying to capture it. Posting to your story or on your own personal page is fine, but if you are attempting to do so for commercial purposes, you will have to answer to the French authorities! The tower's light display is technically an artwork protected by copyright laws.

9. The Hidden Apartment

During construction, architect Gustave Eiffel secretly included a private apartment within his namesake tower. Sitting at 1,000 feet and overlooking Parc du Champ de Mars, this address is quite possibly one of the most interesting in the world! Today it isn't so much a secret as a place to visit and brag about as somewhere you've been!

10. The Weight of the Frame Is 7,300 Tons

The total weight of the Eiffel Tower is a whopping 10,100 tons! That would be the equivalent of 10 cargo ships altogether.

11. Construction Took Two Years, Two Months and Five Days

The construction of the Eiffel Tower demonstrated the sophisticated level of French engineering at the end of the 19th century. Beginning on January 26, 1887, the total construction took two years, two months and five days to complete. The finish date of the tower was a defining moment in the Industrial Era and is largely possible because of its architect, Gustave Eiffel.

12. The Most Visited Monument

With nearly seven million visitors per year, the Eiffel Tower tops the list of the most visited monuments that require payment to see. Since its inception in 1889, there have been close to 300 million visitors from all over the world.

13. Artists Were Against Its Construction

On Valentine's Day in 1887, the Le Temps newspaper included the vehement opposition of over 300 Parisian artists to the Eiffel Tower. The proclamation stated, "We, writers, painters, sculptors, architects, passionate lovers of the beauty, until now intact, of Paris, hereby protest with all our might, with all our indignation, in the name of French taste gone unrecognized, in the name of French art and history under threat, against the construction, in the very heart of our capital, of the useless and monstrous Eiffel Tower.” Their rantings even included that the "gigantic black factory chimney" was so appalling that "even commercial-minded America does not want" it!

14. There Was Once a Laboratory in the Tower

Eiffel installed a laboratory used by himself and the aforementioned 72 scientists to study astronomy, meteorology, aerodynamics and physiology. In 1909, Eiffel established a wind tunnel at the base of the tower to test aerodynamics, including tests done on the Wright Brothers' airplanes and Porsche vehicles.

15. The Tower Moves

Even though the tower was built to withstand natural weather occurrences, the tower can sway during storms. If the weather conditions are bad enough you can even see it move. The sun can cause the tower to expand, as mentioned when the heat causes its height to change, which can make the tower tilt because the sunlight only hits one side of the tower.

16. The Designers of the Tower

Gustave Eiffel is named the architect of this monument, but this was done so because he funded a large portion of the project and eventually purchased the patent rights. Two senior engineers that worked for Eiffel's company are the ones who actually designed it. The engineers Maurice Koechlin and Emile Nouguier worked with French architect Stephen Sauvestre to make the structure more aesthetically pleasing.

17. WWI Achievements

In 1914, the tower housed a radio transmitter that jammed German radio communications and therefore impeded German advancement into Paris. French troops used the tower's wireless station to intercept enemy signals from Berlin, which is thought to have played a significant role in the Allied victory at the First Battle of the Marne.

18. Hitler Ordered Its Destruction

In 1944, Hitler ordered that if Paris could not be held from the Allied liberation, it should be demolished—and the tower along with it. He believed that the destruction of Paris would essentially be the destruction of France. He sent this order to Field Marshal Walther Model and von Choltitz, but when he did, Choltitz was so shocked by the order that he never actually carried it out. Thank goodness!

19. Public Adoration

The 1889 World's Fair was one of the only fairs to turn a profit due to the two million visitors who purchased tickets to see the Eiffel Tower, totaling $1.4 million! Despite the petition from the artists, the public met the tower with great success and adoration.

20. The Tower Can Hold Up to 5,000 Visitors at One Time
