THE EIFFEl TOWER
The Eiffel Tower (French: La Tour Eiffel, [tuʁ ɛfɛl], nickname La dame de fer, the iron lady) is an iron lattice tower located on the Champ de Mars in Paris.
Built in 1889, it has become both a global icon of France and one of the most recognizable structures in the world. The tower is the tallest building in Paris[10] and the most-visited paid monument in the world; millions of people ascend it every year.
Named for its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World`s Fair

The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-story building.
Upon its completion, it surpassed the Washington Monument to assume the title of tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930; however, due to the addition in 1957 of the antenna, the tower is now taller than the Chrysler Building. Not including broadcast antennas, it is the second-tallest structure in France after the 2004 Millau Viaduct
The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs or lift, 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 accessible only by elevator. Both the first and second levels feature restaurants
Design of the tower
Material
The pig iron structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure, including non-metal components, is approximately 10,000 tonnes. As a demonstration of the economy of design, if the 7,300 tonnes of the metal structure were melted down it would fill the 125 metre square base to a depth of only 6 cm (2.36 in), assuming the density of the metal to be 7.8 tonnes per cubic metre. 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.
The tower has become the most prominent symbol of both Paris and France, often in the establishing shot of films set in the city.
