sur Paris, France
Paris is the capital and most populous city of France. Situated on the river Seine in northern metropolitan France, it is in the centre of the Île-de-France region, also known as the région parisienne, "Paris Region". The City of Paris largely retains its one and a half century old administrative boundaries, with an area of 105 km² (41 mi²) and a population of 2,241,346. Together with its suburbs, the whole agglomeration has a population of 10,550,350 (Jan. 2012 census). Paris' metropolitan area spans most of the Île-de-France region and has a population of 12,405,426 (Jan. 2013 census), constituting one-fifth of the population of France. The administrative region covers 12,012 km² (4,638 mi²), with approximately 12 million inhabitants, and has its own regional council and was founded in the 3rd century BC by a Celtic people called the Parisii, who gave the city its name. By the 12th century, Paris was the largest city in the western world, a prosperous trading centre, and the home of the University of Paris, one of the first in Europe. In the 18th century, it was the centre stage for the French Revolution, and became an important centre of finance, commerce, fashion, science, and the arts, a position it still retains today. Since the 19th century, the built-up area of Paris has grown far beyond its administrative borders.
