•History:The Eiffel tower history represents a part of national heritage. It's as been the symbol of France and Paris for decades. But when Gustave Eiffel achived its construction in 1889, the tower was only meant to be temporary in the Parisian landscape and was far from being the parisians' favourite landmark. Without a doubt, the turning point in the Eiffel Tower history took place at the 1889 Universal Exposition. In commemoration of the 100th anniversary of the French Revolution, a competition was organized with the aim to “build on the Champ-de-Mars an iron tower with a square base, 125 meters wide and 300 meters high.” Out of the 107 proposals submitted, Gustave Eiffel’s was chosen. By his side were engineers Maurice Koechlin and Emile Nouguier as well as architect Stephen Sauvestre.
