The risk of accident was great as, unlike modern skyscrapers, the tower is an open frame without any intermediate floors except the two platforms. Three hundred workers joined together 18,038 pieces of puddled iron (a very pure form of structural iron), using two and a half million rivetsMaurice Koechlin.Įiffel was assisted in the design by engineers Émile Nouguier and Maurice Koechlin and architect Stephen Sauvestre. HISTORY The structure was built between 18 as the entrance arch for the Exposition Universelle, a World's Fair marking the centennial celebration of the French Revolution. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7.1 in) because of thermal expansion of the metal on the side facing the sun. As a demonstration of the economy of design, if the 7,300 tonnes of the metal structure were melted down it would fill the 125 metre square base to a depth of only 6 cm (2.36 in), assuming the density of the metal to be 7.8 tonnes per cubic metre. Material The pig iron structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure, including non-metal components, is approximately 10,000 tonnes. Not including broadcast antennas, it is the second-tallest structure in France after the 2004 Millau Viaduct. Upon its completion, it surpassed the Washingto Monument to assume the title of tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930 however, due to the addition in 1957 of the antenna, the tower is now taller than the Chrysler Building. Named for its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World's Fair.įEATURES The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-story building. ![]() The tower is the tallest building in Paris and the most-visited paid monument in the world millions of people ascend it every year. ![]() Built in 1889, it has become both a global icon of France and one of the most recognizable structures in the world.
