Eiffel Tower (Tour Eiffel in French) is a structure built by engineer Frenchman Gustave Eiffel on the occasion of the Universal Exhibition of 1889 in París.Tiene a height of 324 meters with a weight (newly built) of 7,300 tons, while today it is estimated his weight at more than 10,000 (due to the museum, restaurants , stores and shops that now houses). It was envisaged that the tower reaches 350 meters, but the neighbors were scared (by the threat of a tall building and built with little stones could fall) and demonstrated, causing a change in plans. The last 24 meters, correspond to a television antenna that was added much después.Construida in controversy with the artists of the time, who saw her as a monster of steel is undoubtedly regarded as the undisputed symbol of France and Paris in particular, being the most visited monument in the world.The original color of the tower was yellow, but today nothing remains of él.La structure was built between 1887 and 1889 to serve as the entrance arch for the Exposition Universelle, a world's fair organized to commemorate the centenary of the French Revolution. The tower was inaugurated on March 31, 1889, and opened to public on 6 May that año.Cerca 200 workers joined 18,038 pieces of iron, using two bolts and a half million, following the structural design by Maurice Koechlin . The risk of construction accidents was high, because unlike modern skyscrapers the tower is an open structure with no intermediate floors, with the exception of the two platforms. However, thanks to the Eiffel precautions for their workers (which included the use of harnesses), only one died during the installation of elevadores.La tower has a height of 300 meters, without taking into account the antenna TV 24 meters located at the top. According to the temperature, the top of the Eiffel Tower can zoom in or out of the ground about 8 inches due to thermal expansion of the metal that composes. According to the official site of the monument, to reach the top you have to take 1665 steps (Not 1792, that number certainly take some referring to the year of the First Republic). Maintenance of the tower includes applying 50 tonnes of paint every 7 years, in order to protect it from corrosion. Sometimes the paint color is changed, although currently (2005) the tower shows a brown hue. On the first floor, there are consoles that allow voting in the election of future color of the structure.
