The Eiffel Tower is a wrought iron lattice tower on the Champ de Mars in Paris, France. Named after its engineer and designer, Gustave Eiffel; the tower was built as the entrance arch to the 1889 World's Fair.
The tower is 320 meters (1,050 ft) tall, about the same height as an 81-story building. It became the tallest man-made structure globally during its construction, surpassing New York City's Chrysler Building by nearly 200 feet (61 m).

One of the world's greatest wonders, the Eiffel Tower, took only 2 years, 2 months, and 5 days to build. The engineers and architects who made it possible are:
Gustave Eiffel was a French civil engineer. Gustave Eiffel began his career as an engineer working on bridges for the French railway network. One of his most prominent works during this time was the Garabit Viaduct near Millau in southern France. His best-known work, however, might be the Eiffel Tower, which was designed by his company for the 1889 Universal Exposition in Paris. He was also responsible for creating the metal framework for the Statue of Liberty. After his retirement, he focused on research in the fields of meteorology and aerodynamics.
Emile Nouguier and Maurice Koechlin were two of Gustave Eiffel's chief engineers that played an important role in designing and constructing the Eiffel Tower. Koechlin was a graduate of the Zurich Polytechnikum and joined Eiffel's Compagnie des établissements Eiffel in 1879. A graduate of the École Polytechnique was employed by Eiffel et Cie, which later became the Compagnie des établissements Eiffel, in 1867. In 1887, the two engineers started working on the plans for Eiffel Tower.
Stephen Sauvestre was the architect who worked on the appearance of the Eiffel Tower. He was commissioned by Maurice Koechlin and Emile Nouguier, who were concerned about its reception by the public. He added embellishments in the form of decorative arches on the base and the glass pavilion on the first level, and the cupola at the stop. These embellishments made the tower look more impressive. It was these additions that convinced Eiffel, who was hesitant at the start, to go ahead with the project.
The Eiffel Tower, designed by Gustave Eiffel, marked a clear departure from the Neo-Gothic, Neo-Renaissance, and Neo-Baroque styles that were prevalent in the 18th and 19th centuries. The inspiration for the design came from the Latting Observatory built in New York City in 1853.
The original sketch by Keochlin depicted the tower as "a great pylon, consisting of four lattice girders standing apart at the base and coming together at the top, joined together by metal trusses at regular intervals".
The tower is an open-lattice iron structure with four massive arched legs. It is set on masonry columns that curve inward and meet in a single, tapered tower. Each pier rests on four concrete slabs. The tower is made of 18,000 pieces accurate to a tenth of millimeters that has been joined together by 2,500,000 rivets. Each and every piece used in the tower was manufactured especially for it in Eiffel’s factory located at Levallois-Perret on the outskirts of Paris.
French engineer Gustave Eiffel designed the Eiffel Tower to demonstrate that wrought iron could be as strong as stone while being lighter. The tower resembles to the shape of a pyramid but with slightly curved sides. The four-sided tower is divided into four parts based on the height: the lower part, between the floor and the first floor (57.63 m), the second part, between the first and second floor (115.73 m from the ground), the third, between the second and third floor (located at 276.13 m) and the fourth from the third to the top (324 m above ground). The first part is characterized by four distinct pillars, and from the second floor, these pillars merge into a single column that rises to the top.
There are 108 stories with 1,710 steps. However, visitors can only climb stairs to the first platform. There are two elevators—the first powered by hydraulics and the second by electricity. The tower weighs 10,000 tons and has 5 billion lights on it. The Eiffel Tower was one of the first examples of modern architecture because of its use of iron rather than stone or brick.
The material chosen to erect a tower 1,000 feet high was iron for many reasons; it was more realistic than a wooden or stone tower and reinforced concrete was not popular at the time. Puddled iron is created produced in blast furnaces, as a result of which excess carbon is removed. This process makes the iron more durable, and yet lighter and less rigid than steel. The metal framework alone weighs 7,300 tons. In order to extend the lifespan of the tower, it is painted every seven years.
While building such a tall structure, the engineers behind the tower were aware that the tower needed to be able to withstand wind. Eiffel used empirical methods to determine the effects of wind and graphical methods to calculate the strength of the tower. Keeping this in mind, the tower was designed to minimize wind resistance. However, when the winds are strong, the Eiffel Tower sways by up to 9 cm (3.5 in).
Along the frieze that runs along the four sides of the tower, you will find engravings of the names of 72 French scientists, engineers, and mathematicians in recognition of their contributions to the building of the tower. He wanted the future visitors to view the names of those who were behind the creation of this important tower. At the beginning of the 20th century, the engravings were painted over, but they were restored in 1986–87. Unfortunately, not a single name belongs to a woman. Some popular names that appear here include: Monge, Cuvier, Laplace, Ampère, Lavoisier, Gay-Lussac, Arago, Bichat, Daguerre, and Le Verrier.
