In 1884, the French
president decided to launch the 1889 World's Fair in Paris to
celebrate the Republic's 100th anniversary. The idea of building
a tower 300 m high was begun by allowance of spectacular projects
competition Gustave Eiffel bought the patent from his engineers
and his team refined the project with the help of architect
Stephone Sauvestre to compete by his Eiffel Tower. In mid 1886,
a hastily prepared competition lasting 2 weeks (and drawing
107 entries) slected Eiffel's project negotiations could begin
In January 1887, The contract to build the tower was awarded
to Eiffel, who then had two and a half years to complete the
world's tallest structure. Financial condition for the project
awarded Eiffel a subsidy of 1,500,000 Francs (about 20% of total
construction costs), plus the right to exploit the tower commercially
for the duration of the world's fair. At the end of the fair,
the tower would become the property of the city of Paris, but
Eiffel would retain the right to exploit it for a 20 year period.
The genial engineer sensed he was on to a good investment and
he was proved correct. Three hundred metres tall, the Eiffel
Tower was complete for the opening on 31 March 1889, and would
become the fair's major attraction. It was destined to remain
the worlds tallest construction for 42 years until 1930, when
New York Chrysler Building topped it by a metre 18 m. Even after
more than a century, Eiffels tower still draws record crowds-over
5 millon visitors per year, with a total of almost 200 million
since its opening.
The tower later became Paris transmitting antenna for the first
television experiments in 1935. By the outbreak of the second
World War, Paris would have nearly a thousand receivers and
the tower had found a new function it still serves today.
