The Eiffel Tower in Paris was built for the 1889 Universal Exposition (World's Fair) and for the centennial of the French Revolution. Gustave Eiffel, referred to this structure as the 300-Meter Tower, the name "Eiffel Tower" was given by the Parisian critics who were against it and the name has stuck ever since.

In 1889 the elevators were provided by Roux, Combaluzier et Lepape between the ground and 1st platform (located in the east and west legs); Otis built the elevators in the north and south legs serving between ground and second platform. Edoux provided elevators between the second and top platforms.

Cost of construction: 7 400 000 Francs
Fees collected during the world's fair of 1889: 6 500 000 Francs
Subsidy by the city of Paris: 1 500 000 Francs.

121 workers were necessary on site to assemble the tower, while 326 worked at the Eiffel factory.

18 000 different pieces were assembled using 2 500 000 rivets of which 1 050 846 were placed on-site.

During good weather periods, the view is as far as 60 kilometers to the north, 70 km to the West, 55 to the South and 65 to the East.
