For the Exposition Internationale of 1937, the old Palais du Trocadéro was demolished and replaced by the Palais de Chaillot which now tops the hill. It was designed in classicizing "moderne" style by architects Louis-Hippolyte Boileau, Jacques Carlu and Léon Azéma.
Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris. More than 200,000,000 people have visited the tower since its construction in 1889, including 6,719,200 in 2006, making it the most visited paid monument in the world. Including the 24 m (79 ft) antenna, the structure is 324 m (1,063 ft) high (since 2000), which is equivalent to about 81 levels in a conventional building.New York City's Chrysler Building (319 m — 1,047 ft tall) was completed.
The structure was built between 1887 and 1889 as the entrance arch for the Exposition Universelle, a World's Fair marking the centennial celebration of the French Revolution. Eiffel originally planned to build the tower in Barcelona, for the Universal Exposition of 1888, but those responsible at the Barcelona city hall thought it was a strange and expensive construction, which did not fit into the design of the city.
