History and Construction
The Eiffel Tower takes its name from the engineerGustave Eiffelbut was designed by his senior engineersMaurice Koechlin and Emile Nugier. Eiffel sent the engineers to the head of his company’s architectural department, Stephen Sauvestre. With Sauvestre’s edits, Eiffel supported the final plans and bought the patent rights. The tower was built in two years (from 1887 to 1889) just in time for the Universal Exposition. However, not everyone was satisfied. Several prestigious artists and intellectuals of the time decided to mobilize to block its construction but the foundations were completed very quickly. Aware of the historical significance of his Tower, in 1887 Eiffel engaged the photographerEdouard Durandelleto document the work in progress of the Tower.

In 1889, Eiffel was able to complete its construction just in time for the Universal Exposition. It was inaugurated on March 31st, 1889, and officially open to the public. Initially,Eiffelhad been allowed to leave the Tower standing for only 20 years, but given its usefulness for communication reasons and as a laboratory for scientific studies, he was permitted to leave it standing.

Design and data sheet
The French capital’s most precious landmark has an impressiveiron structure of 324 meters high. The only material used for the construction of the Eiffel Tower is the wrought iron that was erected in the shape of a cross in more than 18,000 pieces, fixed together with about 5,000,000 bolts. Its design was firstly created by Maurice Koechlin and Émile Nouguier, two engineers employed in the Compagnie des Éstablissements Eiffel.

The impressive shape and strength of the materials make it weigh about 10,000 tons. For its maintenance, 50 tons of paint are needed every 7 years. Depending on the ambient temperature, the height of the tower can vary by several centimeters due to the expansion of the metal (up to 15 cm higher during the summer heat). On windy days, the top of the tower can oscillate up to 12 cm.
