Eiffel Tower: Information
The Eiffel Tower (French: La Tour Eiffel, [tuʁ ɛfɛl]) is an iron lattice tower located on the Champ de Mars in Paris.
The Eiffel Tower, the iconic Parisian
landmark, was constructed with latticed wrought iron.
Whether you're lucky
enough to have visited Paris or have only ever dreamed of going there, chances
are you know of the French capital's most beloved landmark: the Eiffel Tower.
Construction of Eiffel Tower
The
Eiffel Tower, La Tour Eiffel in French, was the main exhibit of the Paris
Exposition — or World's Fair — of 1889. It was constructed to commemorate the
centennial of the French Revolution and to demonstrate France's industrial
prowess to the world.
World's Fair centerpiece
Gustave
Eiffel, a French civil engineer, is usually credited with designing the tower
that bears his name. However, it was actually two lesser-known men, Maurice
Koechlin and Emile Nouguier, who came up with the original drawings for the
monument.
Kochlin
and Nouguier were the chief engineers for the Compagnie des Establishment
Eiffel — Gustave Eiffel's engineering firm. Together with Eiffel and a French
architect, Stephen Sauvestre, the engineers submitted their plans to a contest
that would determine the centerpiece for the 1889 World's Fair in Paris.
The
Eiffel company's design won, and construction of the wrought iron tower began
in July 1887. But not everyone in Paris was thrilled with the idea of a giant
metal monument looming over the city.
When
construction of the tower began on the Champs de Mars, a group of 300 artists,
sculptors, writers and architects sent a petition to the commissioner of the
Paris Exposition, pleading him to halt construction of the "ridiculous
tower" that would dominate Paris like a "gigantic black
smokestack."
But
the protests of Paris' artistic community fell on deaf ears. Construction of
the tower was completed in just over two years, on March 31, 1889.
Construction of the Eiffel Tower
Each
of the 18,000 pieces used to build the tower was calculated specifically for
the project and prepared in Eiffel's factory on the outskirts of Paris. The
wrought iron structure is composed of four immense arched legs, set on masonry
piers, that curve inward until joining
in a single, tapered tower.
Building
the tower required 2.5 million thermally
assembled rivets and 7,300 tons of iron. To protect the tower from the
elements, workers painted every inch of the structure, a feat that required 60 tons of paint. The tower has since been repainted 18 times.
Eiffel Tower fun facts
- Gustave Eiffel used latticed
wrought iron to construct the tower to demonstrate that the metal could be
as strong as stone while being lighter.
- Gustave Eiffel also created the
internal frame for the Statue of Liberty.
- Construction of the Eiffel Tower cost 7,799,401.31
French gold francs in 1889.
- The Eiffel Tower is 1,063 feet (324 meters) tall,
including the antenna at the top. Without the antenna, it is 984 feet (300
m).
- It was the tallest manmade
structure until the Chrysler
Building was built in New York
in 1930.
- The tower was built to sway
slightly in the wind, but the sun affects the tower more. As the
sun-facing side of the tower heats up, the top moves as much as 7 inches
(18 centimeters) away from the sun.
- The sun also causes the tower
to grow about 6 inches.
- The Eiffel Tower weighs 10,000 tons.
- There are 5 billion lights on the Eiffel Tower.
- The French have a nickname for
the tower: La Dame de Fer, "the Iron Lady."
- The first platform is 190 feet
above the ground; the second platform is 376 feet, and the third platform
is almost 900 feet up.
- The Eiffel Tower has 108 stories, with 1,710 steps.
However, visitors can only climb stairs to the first platform. There are
two elevators.
- One elevator travels a total
distance of 64,001 miles (103,000
kilometers) a year.
Uses of the tower
When
the Compagnie des Establishments Eiffel first won the commission to build a
tower on the Champs de Mars, it was understood that the structure was temporary
and would be removed after 20 years. But Gustave Eiffel was not keen on seeing
his favorite project dismantled, and so he set about making the tower an
indispensable tool for the scientific community.
Just
days after its opening, Eiffel installed a meteorology laboratory on the third
floor of the tower. He invited scientists to use the lab for their studies on
everything from gravity to electricity. Ultimately, however, it was the tower's
looming height, not its laboratory, that saved it from extinction.
In
1910, the city of Paris renewed Eiffel's concession for the tower because of
the structure's usefulness as a wireless telegraph transmitter. The French
military used the tower to communicate wirelessly with ships in the Atlantic
Ocean and intercept enemy messages during World war I.
The
tower is still home to more than 120 antennas, broadcasting both radio and
television signals throughout the capital city and beyond.
