The Eiffel Tower was built by George Eiffel's company. The Eiffel Tower was largely designed by one of Eiffel's employees, Maurice Koechlin, a structural engineer. The Eiffel Tower was built as a monument for the 1889 World's Fair.
Paris hosted the World's Fair in 1889 to mark the 100th anniversary of the French Revolution. The tower was built on the Champ de Mars to be the entrance for the fair. The Eiffel Tower was built with the intention of only being a temporary exhibit and came close to being torn down in 1909. However, the Eiffel Tower was kept standing when Paris city officials noticed that the tower was valuable as a radiotelegraph station.
