The Eiffel Tower stands on the Champ de Mars in Paris, France, next to the Seine River. In order to host the 1889 World's Fair to celebrate the 100th anniversary of the victory of the French Revolution, the French government conducted a construction tender, which resulted in the completion of the Eiffel Tower.


Construction began on January 26, 1887 and was completed on March 31, 1889, making it the tallest building in the world at the time.


It is a masterpiece in the history of world architecture and one of the three major buildings in the West.


The original height of the Eiffel Tower was 312 meters, and it is now 330 meters high. The first floor is 57 meters high and covers an area of ​​4415 square meters, the second floor is 115 meters high and covers an area of ​​1430 square meters, and the third floor is 276 meters high and covers an area of ​​250 square meters.


It used more than 1,500 giant prefabricated beams, 1.5 million rivets, 12,000 steel castings, and no cement. It weighed 7,000 tons and was built by 250 workers in 17 months at a cost of 7.4 million gold francs.


There are five elevators from the plaza to the second floor, and two double elevators from the second floor to the top floor. The tower has five areas: the square, the first floor, the second floor, the top floor and the garden, and receives 7 million tourists every year.


Feature of the Eiffel Tower.


The entire tower structure of the Eiffel Tower is tall and sturdy, narrow at the top and wide at the bottom, giving people a feeling of balance and stability. As large as the entire tower body, as small as each component is symmetrical in the three-dimensional coordinate system.


At the lower beam, the tower has been widened, so the span of the beam is correspondingly increased, its function as a connection is relatively weakened, and the effect of the span is reflected.


In order to further strengthen the connection between the tower column and the beam, make it unified into a whole, and fully reflect the spanning effect of the tower column divergent at the bottom of the tower, a set of huge arches were designed and arranged.


Was the Eiffel Tower also popular in the beginning?


Because Paris, France, is a romantic city, with low-rise and romantic buildings, but this steel-structured building that rises abruptly in the city center makes Parisians very angry.


Parisians have repeatedly wanted to demolish the Eiffel Tower, thinking that it would affect the face of Paris and become the worst and most failed building in Paris, but now it has become the most expensive architectural landmark in France and the world, about 6.98 million in 2011.


In 2010, the cumulative number of tourists exceeded 250 million, bringing Paris 1.5 billion euros in tourism revenue every year. The people of Paris also embraced it and regarded the Eiffel Tower as a symbol of France.


The Eiffel Tower is an architectural marvel because of its unique design.
