Even if you do not want to visit this world-famous structure, you will see its top from all over Paris.The Eiffel Tower was built as the main attraction of the World Exhibition of 1889, held in celebration of the centennial of the French Revolution.A competition was held in 1886 for the design of the centerpiece of the exhibition. The organizers had decided on a 300-meter-tall (around 1,000 ft) tower. The winning design was submitted by the firm of the French engineer Gustave Eiffel, who was known for his revolutionary bridge building techniques, as employed in the great viaduct at Garabit in 1880-1885, and who had just built the iron frame for the Statue of Liberty in New York.
