70-573: The current tower is the second to occupy the site. The original tower, patterned after the Eiffel Tower and the Arc de Triomphe , was built in 1912, and was connected to the adjacent amusement park, Luna Park , by an aerial cable car . At the time of its construction, its height of 64 metres (210 ft) made it the second tallest structure in Asia. It quickly became one of the most popular locations in

140-531: A 100,000-franc prize offered by Henri Deutsch de la Meurthe for the first person to make a flight from St. Cloud to the Eiffel Tower and back in less than half an hour. In 1910, Father Theodor Wulf measured radiant energy at the top and bottom of the tower. He found more at the top than expected, incidentally discovering what are known today as cosmic rays . Two years later, on 4 February 1912, Austrian tailor Franz Reichelt died after jumping from

210-410: A 600 step climb. Although there is a staircase to the top level, it is usually accessible only by lift. On this top, third level is a private apartment built for Gustave Eiffel's personal use. He decorated it with furniture by Jean Lachaise and invited friends such as Thomas Edison . The design of the Eiffel Tower is attributed to Maurice Koechlin and Émile Nouguier , two senior engineers working for

280-417: A block of limestone with an inclined top to bear a supporting shoe for the ironwork. Each shoe was anchored to the stonework by a pair of bolts 10 cm (4 in) in diameter and 7.5 m (25 ft) long. The foundations were completed on 30 June, and the erection of the ironwork began. The visible work on-site was complemented by the enormous amount of exacting preparatory work that took place behind

350-585: A crucial role in intercepting enemy communications from Berlin. In 1914, French forces successfully launched a counter-attack during the Battle of the Marne after gaining critical intelligence on the German Army's movements. In 1917, the station intercepted a coded message between Germany and Spain that referenced 'Operative H-21.' This information contributed to the arrest, conviction, and execution of Mata Hari ,

420-756: A different color set for every two months (e.g. pink for cherry blossom in March/April). Hitachi has sponsored the tower since 1957, and the light designs usually spell out Hitachi advertisements, although one side of the tower is usually occupied by a public service announcement. The lights on top of the tower are a weather beacon indicating tomorrow's weather forecast by a combination of different colors. 34°39′08″N 135°30′22″E  /  34.65222°N 135.50611°E  / 34.65222; 135.50611 Eiffel Tower The Eiffel Tower ( / ˈ aɪ f əl / EYE -fəl ; French : Tour Eiffel [tuʁ ɛfɛl] )

490-420: A factory in the nearby Parisian suburb of Levallois-Perret and were first bolted together, with the bolts being replaced with rivets as construction progressed. No drilling or shaping was done on site: if any part did not fit, it was sent back to the factory for alteration. In all, 18,038 pieces were joined using 2.5 million rivets. At first, the legs were constructed as cantilevers , but about halfway to

560-441: A force of 800 tonnes, and the legs were intentionally constructed at a slightly steeper angle than necessary, being supported by sandboxes on the scaffold. Although construction involved 300 on-site employees, due to Eiffel's safety precautions and the use of movable gangways, guardrails and screens, only one person died. The main structural work was completed at the end of March 1889 and, on 31 March, Eiffel celebrated by leading

630-484: A global cultural icon of France and one of the most recognisable structures in the world. The tower received 5,889,000 visitors in 2022. The Eiffel Tower is the most visited monument with an entrance fee in the world: 6.91 million people ascended it in 2015. It was designated a monument historique in 1964, and was named part of a UNESCO World Heritage Site ("Paris, Banks of the Seine") in 1991. The tower

700-418: A group of government officials, accompanied by representatives of the press, to the top of the tower. Because the lifts were not yet in operation, the ascent was made by foot, and took over an hour, with Eiffel stopping frequently to explain various features. Most of the party chose to stop at the lower levels, but a few, including the structural engineer, Émile Nouguier, the head of construction, Jean Compagnon,

770-550: A height of 300 m, or even 200 m for that matter, and many people believed it was impossible. These objections were an expression of a long-standing debate in France about the relationship between architecture and engineering. It came to a head as work began at the Champ de Mars: a "Committee of Three Hundred" (one member for each metre of the tower's height) was formed, led by the prominent architect Charles Garnier and including some of

840-416: A letter of support written to Alphand, sardonically saying, "Judging by the stately swell of the rhythms, the beauty of the metaphors, the elegance of its delicate and precise style, one can tell this protest is the result of collaboration of the most famous writers and poets of our time", and he explained that the protest was irrelevant since the project had been decided upon months before, and construction on

910-436: A nationalist poem in the shape of the tower (a calligram ) to express his feelings about the war against Germany. Today, it is widely considered to be a remarkable piece of structural art , and is often featured in films and literature. Work on the foundations started on 28 January 1887. Those for the east and south legs were straightforward, with each leg resting on four 2 m (6.6 ft) concrete slabs, one for each of

980-540: A result of the Haitian Revolution , and required Haiti to pay the CIC and its partner nearly half of all taxes collected on exports, "effectively choking off the nation's primary source of income". According to The New York Times , "[at] a time when the [CIC] was helping finance one of the world's best-known landmarks, the Eiffel Tower, as a monument to French liberty, it was choking Haiti's economy, taking much of

1050-460: A year, and in 1957, the present radio aerial was added to the top. In 1964, the Eiffel Tower was officially declared to be a historical monument by the Minister of Cultural Affairs, André Malraux . A year later, an additional lift system was installed in the north pillar. According to interviews, in 1967, Montreal Mayor Jean Drapeau negotiated a secret agreement with Charles de Gaulle for

1120-656: Is 330 metres (1,083 ft) tall, about the same height as an 81-storey building, and the tallest structure in Paris . Its base is square, measuring 125 metres (410 ft) on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest human-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City

1190-677: Is a wrought-iron lattice tower on the Champ de Mars in Paris , France. It is named after the engineer Gustave Eiffel , whose company designed and built the tower from 1887 to 1889. Locally nicknamed " La dame de fer " (French for "Iron Lady"), it was constructed as the centerpiece of the 1889 World's Fair , and to crown the centennial anniversary of the French Revolution . Although initially criticised by some of France's leading artists and intellectuals for its design, it has since become

1260-575: The Crédit Industriel et Commercial (CIC), helped finance the construction of the Eiffel Tower. During the period of the tower's construction, the CIC was acquiring funds from predatory loans to the National Bank of Haiti , some of which went towards the financing of the tower. These loans were connected to an indemnity controversy that saw France force Haiti's government to financially compensate French slaveowners for lost income as

1330-528: The 1900 Exposition Universelle , the lifts in the east and west legs were replaced by lifts running as far as the second level constructed by the French firm Fives-Lille. These had a compensating mechanism to keep the floor level as the angle of ascent changed at the first level, and were driven by a similar hydraulic mechanism as the Otis lifts, although this was situated at the base of the tower. Hydraulic pressure

1400-539: The City of Paris . The city had planned to tear it down (part of the original contest rules for designing a tower was that it should be easy to dismantle) but as the tower proved to be valuable for many innovations in the early 20th century, particularly radio telegraphy , it was allowed to remain after the expiry of the permit, and from 1910 it also became part of the International Time Service. For

1470-472: The Compagnie des Établissements Eiffel . It was envisioned after discussion about a suitable centerpiece for the proposed 1889 Exposition Universelle , a world's fair to celebrate the centennial of the French Revolution . In May 1884, working at home, Koechlin made a sketch of their idea, described by him as "a great pylon, consisting of four lattice girders standing apart at the base and coming together at

1540-481: The ambient temperature , the top of the tower may shift away from the sun by up to 18 cm (7 in) due to thermal expansion of the metal on the side facing the sun. When it was built, Eiffel was accused of trying to create something artistic with no regard to the principles of engineering. However, Eiffel and his team were experienced bridge builders. In an interview with the newspaper Le Temps published on 14 February 1887, Eiffel said: Is it not true that

1610-445: The Champ de Mars. (A 300-metre tower was then considered a herculean engineering effort.) On 12 May, a commission was set up to examine Eiffel's scheme and its rivals, which, a month later, decided that all the proposals except Eiffel's were either impractical or lacking in details. After some debate about the exact location of the tower, a contract was signed on 8 January 1887. Eiffel signed it acting in his own capacity rather than as

1680-427: The Eiffel Tower began hosting a seasonal ice rink on the first level. A glass floor was installed on the first level during the 2014 refurbishment. The puddle iron (wrought iron) of the Eiffel Tower weighs 7,300 tonnes , and the addition of lifts, shops and antennae have brought the total weight to approximately 10,100 tonnes. As a demonstration of the economy of design, if the 7,300 tonnes of metal in

1750-873: The Louvre, the Dome of les Invalides, the Arc de Triomphe, all of our humiliated monuments will disappear in this ghastly dream. And for twenty years   ... we shall see stretching like a blot of ink the hateful shadow of the hateful column of bolted sheet metal. Gustave Eiffel responded to these criticisms by comparing his tower to the Egyptian pyramids : "My tower will be the tallest edifice ever erected by man. Will it not also be grandiose in its way? And why would something admirable in Egypt become hideous and ridiculous in Paris?" These criticisms were also dealt with by Édouard Lockroy in

1820-546: The President of the City Council, and reporters from Le Figaro and Le Monde Illustré , completed the ascent. At 2:35 pm, Eiffel hoisted a large Tricolour to the accompaniment of a 25-gun salute fired at the first level. There was still work to be done, particularly on the lifts and facilities, and the tower was not opened to the public until nine days after the opening of the exposition on 6 May; even then,

1890-461: The aesthetic argument for the tower: "Do not the laws of natural forces always conform to the secret laws of harmony?" Some of the protesters changed their minds when the tower was built; others remained unconvinced. Guy de Maupassant supposedly ate lunch in the tower's restaurant every day because it was the one place in Paris where the tower was not visible. By 1918, it had become a symbol of Paris and of France after Guillaume Apollinaire wrote

1960-517: The city, drawing visitors from all over the area. The original structure suffered a fire in 1943 which severely damaged it, and rather than repair the structure, it was disassembled and the steel used for the war effort. After the war, citizens lobbied to rebuild the beloved tower. A private company, the Tsūtenkaku Kanko Co. Ltd. was established and Tachū Naitō , Japan's "Father of Towers" was selected to design it. The new, eight-sided structure

2030-399: The eyes of the observer the boldness of the design as a whole. He used graphical methods to determine the strength of the tower and empirical evidence to account for the effects of wind, rather than a mathematical formula. Close examination of the tower reveals a basically exponential shape. All parts of the tower were overdesigned to ensure maximum resistance to wind forces. The top half

2100-400: The famous spy accused of working for Germany. From 1925 to 1934, illuminated signs for Citroën adorned three of the tower's sides, making it the tallest advertising space in the world at the time. In April 1935, the tower was used to make experimental low-resolution television transmissions, using a shortwave transmitter of 200 watts power. On 17 November, an improved 180-line transmitter

2170-478: The first and second levels. The top level's upper platform is 276 m (906 ft) above the ground—the highest observation deck accessible to the public in the European Union . Tickets can be purchased to ascend by stairs or lift to the first and second levels. The climb from ground level to the first level is over 300 steps, as is the climb from the first level to the second, making the entire ascent

2240-399: The first level construction was paused to create a substantial timber scaffold . This renewed concerns about the structural integrity of the tower, and sensational headlines such as "Eiffel Suicide!" and "Gustave Eiffel Has Gone Mad: He Has Been Confined in an Asylum" appeared in the tabloid press. Multiple famous artists of that time, Charles Garnier and Alexander Dumas , thought poorly of

2310-514: The first level of the tower (a height of 57 m) to demonstrate his parachute design. In 1914, at the outbreak of World War I , a radio transmitter located in the tower jammed German radio communications, seriously hindering their advance on Paris and contributing to the Allied victory at the First Battle of the Marne . During World War I , the Eiffel Tower's wireless station played

2380-559: The greatest respect and admiration for all Engineers including the Great Engineer the Bon Dieu, Thomas Edison. Eiffel made use of his apartment at the top of the tower to carry out meteorological observations , and also used the tower to perform experiments on the action of air resistance on falling bodies. Eiffel had a permit for the tower to stand for 20 years. It was to be dismantled in 1909, when its ownership would revert to

2450-417: The guides for the lifts which were to be fitted in the four legs. The critical stage of joining the legs at the first level was completed by the end of March 1888. Although the metalwork had been prepared with the utmost attention to detail, provision had been made to carry out small adjustments to precisely align the legs; hydraulic jacks were fitted to the shoes at the base of each leg, capable of exerting

2520-484: The hitherto untouched beauty of Paris, protest with all our strength, with all our indignation in the name of slighted French taste, against the erection   ... of this useless and monstrous Eiffel Tower   ... To bring our arguments home, imagine for a moment a giddy, ridiculous tower dominating Paris like a gigantic black smokestack, crushing under its barbaric bulk Notre Dame, the Tour Saint-Jacques,

2590-485: The hour. The lights sparkled blue for several nights to herald the new millennium on 31 December 2000. The sparkly lighting continued for 18 months until July 2001. The sparkling lights were turned on again on 21 June 2003, and the display was planned to last for 10 years before they needed replacing. The tower received its 200,000,000th guest on 28 November 2002. The tower has operated at its maximum capacity of about 7 million visitors per year since 2003. In 2004,

2660-404: The lifts had not been completed. The tower was an instant success with the public, and nearly 30,000 visitors made the 1,710-step climb to the top before the lifts entered service on 26 May. Tickets cost 2 francs for the first level, 3 for the second, and 5 for the top, with half-price admission on Sundays, and by the end of the exhibition there had been 1,896,987 visitors. After dark, the tower

2730-471: The most important figures of the arts, such as William-Adolphe Bouguereau , Guy de Maupassant , Charles Gounod and Jules Massenet . A petition called "Artists against the Eiffel Tower" was sent to the Minister of Works and Commissioner for the Exposition, Adolphe Alphand , and it was published by Le Temps on 14 February 1887: We, writers, painters, sculptors, architects and passionate devotees of

2800-433: The newly made tower. Charles Garnier thought it was a "truly tragic street lamp". Alexander Dumas said that it was like "Odius shadow of the odious column built of rivets and iron plates extending like a black blot". There were multiple protests over the style and the reasoning of placing it in the middle of Paris. At this stage, a small "creeper" crane designed to move up the tower was installed in each leg. They made use of

2870-642: The order. On 25 August, before the Germans had been driven out of Paris , the German flag was replaced with a Tricolour by two men from the French Naval Museum , who narrowly beat three men led by Lucien Sarniguet, who had lowered the Tricolour on 13 June 1940 when Paris fell to the Germans. A fire started in the television transmitter on 3 January 1956, damaging the top of the tower. Repairs took

2940-424: The original water hydraulics were retained solely as a counterbalance system. A service lift was added to the south pillar for moving small loads and maintenance personnel three years later. Robert Moriarty flew a Beechcraft Bonanza under the tower on 31 March 1984. In 1987, A. J. Hackett made one of his first bungee jumps from the top of the Eiffel Tower, using a special cord he had helped develop. Hackett

3010-403: The principal girders of each leg. The west and north legs, being closer to the river Seine , were more complicated: each slab needed two piles installed by using compressed-air caissons 15 m (49 ft) long and 6 m (20 ft) in diameter driven to a depth of 22 m (72 ft) to support the concrete slabs, which were 6 m (20 ft) thick. Each of these slabs supported

3080-404: The public between November and March because the water in the hydraulic drive tended to freeze. The new cars operate in pairs, with one counterbalancing the other, and perform the journey in one stage, reducing the journey time from eight minutes to less than two minutes. At the same time, two new emergency staircases were installed, replacing the original spiral staircases. In 1983, the south pillar

3150-428: The representative of his company, the contract granting him 1.5 million francs toward the construction costs: less than a quarter of the estimated 6.5 million francs. Eiffel was to receive all income from the commercial exploitation of the tower during the exhibition and for the next 20 years. He later established a separate company to manage the tower, putting up half the necessary capital himself. A French bank,

3220-527: The rights to the patent on the design which Koechlin, Nouguier, and Sauvestre had taken out, and the design was put on display at the Exhibition of Decorative Arts in the autumn of 1884 under the company name. On 30 March 1885, Eiffel presented his plans to the Société des Ingénieurs Civils ; after discussing the technical problems and emphasising the practical uses of the tower, he finished his talk by saying

3290-497: The scenes: the drawing office produced 1,700 general drawings and 3,629 detailed drawings of the 18,038 different parts needed. The task of drawing the components was complicated by the complex angles involved in the design and the degree of precision required: the position of rivet holes was specified to within 1 mm (0.04 in) and angles worked out to one second of arc . The finished components, some already riveted together into sub-assemblies, arrived on horse-drawn carts from

3360-426: The structure were melted down, it would fill the square base, 125 metres (410 ft) on each side, to a depth of only 6.25 cm (2.46 in) assuming the density of the metal to be 7.8 tonnes per cubic metre. Additionally, a cubic box surrounding the tower (324 m × 125 m × 125 m) would contain 6,200 tonnes of air, weighing almost as much as the iron itself. Depending on

3430-457: The top, joined together by metal trusses at regular intervals". Eiffel initially showed little enthusiasm, but he did approve further study, and the two engineers then asked Stephen Sauvestre , the head of the company's architectural department, to contribute to the design. Sauvestre added decorative arches to the base of the tower, a glass pavilion to the first level, and other embellishments. The new version gained Eiffel's support: he bought

3500-449: The tower in 1979. The statue of Billiken became closely associated with the tower and is a popular symbol of good luck. Each year thousands of visitors place a coin in his donation box and rub the soles of his feet to make their wishes come true. The tower is also famous for its neon lights , which change every few years (they were shut off during the oil crisis of 1974–76 ). The neon lights have now been replaced by LED lighting , showing

3570-482: The tower lost the title of the world's tallest structure when the Chrysler Building in New York City was completed. In 1938, the decorative arcade around the first level was removed. Upon the German occupation of Paris in 1940, the lift cables were cut by the French. The tower was restricted to German visitors during the occupation and the lifts were not repaired until 1946. In 1940, German soldiers had to climb

3640-444: The tower to be dismantled and temporarily relocated to Montreal to serve as a landmark and tourist attraction during Expo 67 . The plan was allegedly vetoed by the company operating the tower out of fear that the French government could refuse permission for the tower to be restored in its original location. In 1982, the original lifts between the second and third levels were replaced after 97 years in service. These had been closed to

When visiting Paris, Hitler chose to stay on the ground. When the Allies were nearing Paris in August 1944, Hitler ordered General Dietrich von Choltitz , the military governor of Paris, to demolish the tower along with the rest of the city. Von Choltitz disobeyed

3780-501: The tower was already under way. Garnier was a member of the Tower Commission that had examined the various proposals, and had raised no objection. Eiffel pointed out to a journalist that it was premature to judge the effect of the tower solely on the basis of the drawings, that the Champ de Mars was distant enough from the monuments mentioned in the protest for there to be little risk of the tower overwhelming them, and putting

Little progress was made until 1886, when Jules Grévy

3990-430: The tower. During the last three minutes of the year, the lights were turned on starting from the base of the tower and continuing to the top to welcome 2000 with a huge fireworks show. An exhibition above a cafeteria on the first floor commemorates this event. The searchlights on top of the tower made it a beacon in Paris's night sky, and 20,000 flashing bulbs gave the tower a sparkly appearance for five minutes every hour on

4060-471: The very conditions which give strength also conform to the hidden rules of harmony?   ... Now to what phenomenon did I have to give primary concern in designing the Tower? It was wind resistance. Well then! I hold that the curvature of the monument's four outer edges, which is as mathematical calculation dictated it should be   ... will give a great impression of strength and beauty, for it will reveal to

A one devised in 2004 after letters sent by Eiffel to the French Society of Civil Engineers in 1885 were translated into English described it as a non-linear integral equation based on counteracting the wind pressure on any point of

4410-594: Was finished in 1930. It was the first structure in the world to surpass both the 200-metre and 300-metre mark in height. Due to the addition of a broadcasting aerial at the top of the tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Excluding transmitters, the Eiffel Tower is the second tallest free-standing structure in France after the Millau Viaduct . The tower has three levels for visitors, with restaurants on

4480-467: Was fitted with an electrically driven Otis lift to serve the Jules Verne restaurant. The Fives-Lille lifts in the east and west legs, fitted in 1899, were extensively refurbished in 1986. The cars were replaced, and a computer system was installed to completely automate the lifts. The motive power was moved from the water hydraulic system to a new electrically driven oil-filled hydraulic system, and

4550-472: Was installed. On two separate but related occasions in 1925, the con artist Victor Lustig "sold" the tower for scrap metal. A year later, in February 1926, pilot Leon Collet was killed trying to fly under the tower. His aircraft became entangled in an aerial belonging to a wireless station. A bust of Gustave Eiffel by Antoine Bourdelle was unveiled at the base of the north leg on 2 May 1929. In 1930,

4620-440: Was lit by hundreds of gas lamps, and a beacon sent out three beams of red, white and blue light. Two searchlights mounted on a circular rail were used to illuminate various buildings of the exposition. The daily opening and closing of the exposition were announced by a cannon at the top. On the second level, the French newspaper Le Figaro had an office and a printing press, where a special souvenir edition, Le Figaro de la Tour ,

4690-519: Was made. At the top, there was a post office where visitors could send letters and postcards as a memento of their visit. Graffitists were also catered for: sheets of paper were mounted on the walls each day for visitors to record their impressions of the tower. Gustave Eiffel described the collection of responses as "truly curious". Famous visitors to the tower included the Prince of Wales , Sarah Bernhardt , "Buffalo Bill" Cody (his Wild West show

4760-550: Was opened in 1956. On the fifth floor observation deck is enshrined Billiken , the God of Happiness or "things as they ought to be". Billiken, a popular American charm doll that came to Japan in about 1910, was enshrined within Luna Park when it opened. When the park closed in 1923, the wooden statue of Billiken went missing. As a part of an effort to revive the tower, a copy of Billiken was made from an old photograph and placed inside
