On the occasion of the Universal Exhibition of 1889, which marked the centenary of the French Revolution, a great competition was launched, won by the industrialist Gustave Eiffel, much to the chagrin of many artists of the time including the writer Guy de Maupassant.
Built in two years, two months and five days, the one based on more than 18,000 pieces of iron is the symbol of a "technical and architectural performance". In the nineteenth century, "it is the symbol of a France that catches up with its industrial power" and becomes "the highlight of the 1889 exhibition," said Bertrand Lemoine, architect and historian.
