The Eiffel Tower, Paris

Paris (ⁱ/ˈpærɨs/; French: [paʁi] ( listen)) is the capital and largest city of France. It is situated on the river Seine, in northern France, at the heart of the Île-de-France region (or Paris Region, French: Région parisienne). The city of Paris, within its administrative limits (the 20 arrondissements) largely unchanged since 1860, has an estimated population of 2,211,297 (January 2008), but the Paris metropolitan area has a population of 12,089,098 (January 2008), and is one of the most populated metropolitan areas in Europe. Paris was the largest city in the Western world for about 1,000 years, prior to the 19th century, and the largest in the entire world between the 16th and 19th centuries.

The Eiffel Tower (French: La Tour Eiffel, [tuʁ ɛfɛl], nickname La dame de fer, the iron lady) is a wrought iron lattice tower located on the Champ de Mars in Paris. Built in 1889 as the entrance arch to the 1889 World's Fair, it has become both a global cultural icon of France and one of the most recognizable structures in the world. The tower is the tallest building in Paris and the most-visited paid monument in the world; millions of people ascend it every year. It is named after the engineer Gustave Eiffel, whose company designed and built the tower.

The tower stands 320 metres (1,050 ft) tall, about the same height as an 81-story building. During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the 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, because of the addition, in 1957, of the antenna atop the Eiffel Tower, it is now taller than the Chrysler Building. Not including broadcast antennas, it is the second-tallest structure in France, after the Millau Viaduct.
