The Eiffel
Tower
The Eiffel Tower
is a 19th century iron lattice tower located on the Champ de Mars in
Paris that has become both a global icon of France and one of the most
recognizable structures in the world. The Eiffel Tower,
which is the tallest building in Paris,[1] is the single most visited paid
monument in the world; millions of people ascend it every year. Named after its
designer, engineer Gustave Eiffel, the tower was built as the entrance arch for
the 1889 World's Fair.
The tower stands at
324 m (1,063 ft) tall, about the same height as an 81-story building. It was
the tallest structure in the world from its completion until 1930, when it was
eclipsed by the Chrysler Building in New York City. Not including broadcast
antennas, it is the second-tallest structure in France, behind the Millau
Viaduct, completed in 2004. And while the Eiffel Tower is a steel structure,
and weighs approximately 10,000 tonnes, it actually has a relatively low
density, weighing less than a cylinder of air occupying the same dimensions as
the tower.
The tower has three
levels for visitors. Tickets can be purchased to ascend either on stairs or
lifts to the first and second levels. The walk to the first level is over 300
steps, as is the walk from the first to the second level. The third and highest
level is only accessible by lift. Both the first and second levels feature
restaurants.
The tower has
become the most prominent symbol of both Paris and France. The tower is a
featured part of the backdrop in literally scores of movies that take place in
Paris. Its iconic status is so established that it even serves as a symbol for
the entire nation of France, such as when it was used as the logo for the
French bid to host the 1992 Summer Olympics.
The metal structure of the Eiffel Tower weighs 7,300 tonnes
while the entire structure including non-metal components is approximately
10,000 tonnes. Depending on the ambient temperature, the top of the tower may
shift away from the sun by up to 18 cm (7.1 in) because of thermal expansion of
the metal on the side facing the sun. As demonstration of the economy of
design, if the 7300 tonnes of the metal structure were melted down it would
fill the 125 meter square base to a depth of only 6 cm (2.36 in), assuming a
density of the metal to be 7.8 tonnes per cubic meter. The tower has a mass
less than the mass of the air contained in a cylinder of the same dimensions,
that is 324 meters high and 88.3 meters in radius. The weight of the tower is
10,100 tonnes compared to 10,265 tonnes of air.
