The Diffel Tower (pronounced /'aifəl'taʊɚ/; French: La Tour Eiffel, pronounced /'tur,e'fel/) is an iron tower built on the Champ de Mars beside the River Seine in Paris. It is the tallest structure in Paris and possibly the most recognized symbol in the world[1]. Named after its designer, engineer Gustave Eiffel, it is the most visited monument in the world; 6,428,441 people visited the tower in 2005[2] and more than 200,000,000 since its construction [3]. Including the 20.75 m (70 ft) antenna, the structure is 320.75 m (1070 ft) high which is about 81 stories. In 1902, it was struck by lightning, which caused builders to reconstruct 300 feet of the top. The lights illuminating the tower also had to be replaced, due to short-circuiting.
At the time of its construction in 1889, the tower replaced the Washington Monument as the world's tallest structure in the world, a title it retained until 1930, when New York City's Chrysler Building (1063.33 ft tall) was completed[4]. The tower is now the fifth-highest structure in France[citation needed]. The Eiffel Tower is the highest structure in Paris, with the second-highest being the Tour Montparnasse.
The structure of the Eiffel Tower weighs 7,300 tons[5]. There are 1660 steps[6]. It is not possible for the public to reach the summit via the stairs, lifts are required beyond the second platform.
Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 3.25 inches, due to thermal expansion of the metal on the side facing the sun[citation needed].
Maintenance of the tower includes applying 50/60 tons of three graded tones of paint every seven years to protect it from rust. On occasion, the color of the paint is changed — the tower is currently painted a shade of brownish-gray. However, few people realize that the tower is actually painted three different colors in order to make it look the same color. The colors change from dark to light from top to bottom, but it looks the same because of the background (the sky being light and the ground being dark)[7]. On the first floor, there are interactive consoles hosting a poll for the color to use for a future session of painting. The co-architech of the Eiffel Tower are Emile Naugier, Maurice Koechlin and Stephen Sauvestre[8].
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. It is located at geographic coordinates 48°51′29″N, 2°17′40″E. The tower was inaugurated on March 31, 1889, and opened on May 6th. Three hundred workers joined together 18,038 pieces of puddled iron (a very pure form of structural iron), using three and a half million rivets, in a structural design by Maurice Koechlin. The risk of accident was great, for unlike modern skyscrapers the tower is an open frame without any intermediate floors except the two platforms. Yet because Eiffel took safety precautions including use of movable stagings, guard-rails and screens, only one man died, during the installation of Otis Elevator's lifts.
The tower was met with resistance from the public when it was built, with many calling it an eyesore. (Novelist Guy de Maupassant ate at a restaurant at the tower regularly, because it was the one place in Paris he was sure he wouldn't see it. Today, it is widely considered to be a striking piece of structural art.
艾菲爾鐵塔(法語:La Tour Eiffel)是一座於1889年建成位於法國巴黎戰神廣場上的鏤空結構鐵塔,高300米,天線高24米,總高324米。艾菲爾鐵塔得名於設計它的橋樑工程師居斯塔夫·艾菲爾。鐵塔設計新穎獨特,是世界建築史上的技術傑作,因而成為法國和巴黎的一個重要景點和突出標誌。
艾菲爾鐵塔從1887年起建,分為三樓,分別在離地面57.6米、115.7米和276.1米處,其中一、二樓設有餐廳,第三樓建有觀景台,從塔座到塔頂共有1711級階梯,共用去鋼鐵7000噸,12000個金屬部件,250萬隻鉚釘。
1889年5月15日,為給世界博覽會開幕式剪綵,鐵塔的設計師居斯塔夫·艾菲爾親手將法國國旗升上鐵塔的300米高空,由此,人們為了紀念他對法國和巴黎的這一貢獻,特別還在塔下為他塑造了一座半身銅像。
直到2004年1月16日,為申辦2012年夏季奧運會,法國巴黎市政府特意在艾菲爾鐵塔上介紹了其為申奧所做出的準備情況,而艾菲爾鐵塔更成為了該國申奧的「天然廣告」。
日出的艾菲爾鐵塔這個為了世界博覽會而落成的金屬建築, 曾經保持世界最高建築45年, 直到紐約帝國大廈的出現。 它由150萬個鉚釘連接固定, 據說它對地面的壓強只有一個人坐在椅子上那麼大。塔的四個面上, 銘刻了72個科學家的名字, 都是為了保護鐵塔不被摧毀而從事研究的人們。 徒步登塔可以上第一層和第二層, 3.8歐, 坐纜車上第一層4.2歐, 第二層7.7歐, 最頂尖11歐, 在此可以放眼巴黎全城。
戰神廣場的另一端有和平門和和平碑, 上面用不同的文字寫著"和平", 表達了人們美好的願望.
