The Eiffel Tower

By wiki!

The Eiffel Tower (FrenchTour Eiffel[tuʀ ɛfɛl]) is a 19th century iron lattice tower located on the Champ de Mars in Paris that has become both a global icon of France and one of the most recognizable structures in the world. The Eiffel Tower, which is the tallest building in Paris,[1]is the single most visited paid monument in the world; millions of people ascend it every year. Named after its designer, engineer Gustave Eiffel, the tower was built as the entrance arch for the 1889 World’s Fair.

The tower stands at 324 m (1,063 ft) tall, about the same height as an 81-story building. It was the tallest structure in the world from its completion until 1930, when it was eclipsed by the Chrysler Building in New York City. Not including broadcast antennas, it is the second-tallest structure in France, behind the Millau Viaduct, completed in 2004. And while the Eiffel Tower is a steel structure, and weighs approximately 10,000 tonnes, it actually has a relatively low density, weighing less than a cylinder of air occupying the same dimensions as the tower.

The tower has three levels for visitors. Tickets can be purchased to ascend either on stairs or lifts to the first and second levels. The walk to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by lift. Both the first and second levels feature restaurants.

The tower has become the most prominent symbol of both Paris and France. The tower is a featured part of the backdrop in literally scores of movies that take place in Paris. Its iconic status is so established that it even serves as a symbol for the entire nation of France, such as when it was used as the logo for the French bid to host the 1992 Summer Olympics.


The structure was built between 1887 and 1889 as the entrance arch for the Exposition Universelle, a World’s Fair marking the centennial celebration of the French Revolution. Eiffel originally planned to build the tower in Barcelona, for the Universal Exposition of 1888, but those responsible at the Barcelona city hall thought it was a strange and expensive construction, which did not fit into the design of the city. After the refusal of the Consistory of Barcelona, Eiffel submitted his draft to those responsible for the Universal Exhibition in Paris, where he would build his tower a year later, in 1889. The tower was inaugurated on 31 March 1889, and opened on 6 May. Three hundred workers joined together 18,038 pieces of puddled iron (a very pure form of structural iron), using two and a half million rivets, in a structural design by Maurice Koechlin. The risk of accident was great, for unlike modernskyscrapers the tower is an open frame without any intermediate floors except the two platforms. However, because Eiffel took safety precautions, including the use of movable stagings, guard-rails and screens, only one man died.

The tower was met with much criticism from the public when it was built, with many calling it an eyesore. Newspapers of the day were filled with angry letters from the arts community of Paris. One is quoted extensively in William Watson’s US Government Printing Office publication of 1892 Paris Universal Exposition: Civil Engineering, Public Works, and Architecture. “And during twenty years we shall see, stretching over the entire city, still thrilling with the genius of so many centuries, we shall see stretching out like a black blot the odious shadow of the odious column built up of riveted iron plates.”[2] Signers of this letter included Jean-Louis-Ernest MeissonierCharles GounodCharles GarnierJean-Léon GérômeWilliam-Adolphe Bouguereau, and Alexandre Dumas.

Novelist Guy de Maupassant—who claimed to hate the tower[3]—supposedly ate lunch in the Tower’s restaurant every day. When asked why, he answered that it was the one place in Paris where one could not see the structure. Today, the Tower is widely considered to be a striking piece of structural art.

One of the great Hollywood movie clichés is that the view from a Parisian window always includes the tower. In reality, since zoning restrictions limit the height of most buildings in Paris to 7 stories, only a very few of the taller buildings have a clear view of the tower.

Eiffel had a permit for the tower to stand for 20 years, meaning it would have had to be dismantled in 1909, when its ownership would revert to theCity of Paris. The City had planned to tear it down (part of the original contest rules for designing a tower was that it could be easily demolished) but as the tower proved valuable for communication purposes, it was allowed to remain after the expiration of the permit. The military used it to dispatch Parisian taxis to the front line during the First Battle of the Marne, and it therefore became a victory statue of that battle.

The co-architects of the Eiffel Tower were Emile Nouguier, Maurice Koechlin and Stephen Sauvestre.

History of modern Architecture

Modern architecture is characterized by simplification of form and creation of ornament from the structure and theme of the building. The first variants were conceived early in the 20th century. Modern architecture was adopted by many influential architects and architectural educators, however very few “Modern buildings” were built in the first half of the century. It gained popularity after the Second World War and became the dominant architectural style for institutional and corporate buildings for three decades.

The exact characteristics and origins of Modern architecture are still open to interpretation and debate.


Some historians see the evolution of Modern architecture as a social matter, closely tied to the project of Modernity and thus the Enlightenment. The Modern style developed, in their opinion, as a result of social and political revolutions.

Others see Modern architecture as primarily driven by technological and engineering developments, and it is true that the availability of new building materials such as ironsteel, and glass drove the invention of new building techniques as part of the Industrial Revolution. In 1796, Shrewsbury mill owner Charles Bage first used his ‘fireproof‘ design, which relied on cast iron and brick with flag stone floors. Such construction greatly strengthened the structure of mills, which enabled them to accommodate much bigger machines. Due to poor knowledge of iron’s properties as a construction material, a number of early mills collapsed. It was not until the early 1830s that Eaton Hodgkinson introduced the section beam, leading to widespread use of iron construction, this kind of austere industrial architecture utterly transformed the landscape of northern Britain, leading to the description of places like Manchester and parts of West Yorkshire as “Dark satanic mills”.

The Crystal Palace by Joseph Paxton at the Great Exhibition of 1851 was an early example of iron and glass construction; possibly the best example is the development of the tall steel skyscraper in Chicago around 1890 by William Le Baron Jenney and Louis Sullivan. Early structures to employ concrete as the chief means of architectural expression (rather than for purely utilitarian structure) include Frank Lloyd Wright’s Unity Temple, built in 1906 near Chicago, andRudolf Steiner’s Second Goetheanum, built from 1926 near BaselSwitzerland.

Other historians regard Modernism as a matter of taste, a reaction against eclecticism and the lavish stylistic excesses of Victorian Era and Edwardian Art Nouveau. Note that the Russian word for Art Nouveau, “Модерн”, and the Spanish word for Art Nouveau, “Modernismo” are cognates of the English word “Modern” though they carry different meanings.

Whatever the cause, around 1900 a number of architects around the world began developing new architectural solutions to integrate traditional precedents (Gothic, for instance) with new technological possibilities. The work of Louis Sullivan and Frank Lloyd Wright in Chicago, Victor Horta in Brussels, Antoni Gaudi in Barcelona, Otto Wagner in Vienna and Charles Rennie Mackintosh in Glasgow, among many others, can be seen as a common struggle between old and new. An early use of the term in print around this time, approaching its later meaning, was in the title of a book by Otto Wagner.[2][3]

A key organization that spans the ideals of the Arts and Crafts and Modernism as it developed in the 1920s was the Deutscher Werkbund (German Work Federation) a German association of architects, designers and industrialists. It was founded in 1907 in Munich at the instigation of Hermann Muthesius. Muthesius was the author of a three-volume “The English House” of 1905, a survey of the practical lessons of the English Arts and Crafts movement and a leading political and cultural commentator. The purpose of the Werkbund was to sponsor the attempt to integrate traditional crafts with the techniques of industrial mass production. The organization originally included twelve architects and twelve business firms, but quickly expanded. The architects include Peter BehrensTheodor Fischer (who served as its first president), Josef Hoffmann and Richard Riemerschmid. Joseph August Lux, an Austrian-born critic, helped formulate its agenda.

Modern architecture is usually characterized by:

  • an adoption of the principle that the materials and functional requirements determine the result
  • an adoption of the machine aesthetic
  • an emphasis of horizontal and vertical lines
  • a creation of ornament using the structure and theme of the building, or a rejection of ornamentation.
  • a simplification of form and elimination of “unnecessary detail”
  • an adoption of expressed structure
  • Form follows function

A growing trend in modern architecture is the move towards sustainability of design. Most buildings generate an average of 3.9 pounds of waste per square foot[10]. On a large building, that can add up to over one hundred tons. This has led many architects to develop ways to design structures that inherently have less waste, such as by creating spaces whose dimensions are based on standard material dimensions. Thus, constructors do not have to work the material into the proper shape, which saves both resources and money. In the United States, many new buildings are being designed to LEED standards with “green” details such as photovoltaic panels, green roofs, and natural lighting and ventilation.
