Paris

Paris is the capital of France and the country's most populous city. It is situated on the river Seine, in northern France, at the heart of the Île-de-France region. The city of Paris, within its administrative limits largely unchanged since 1860 and is one of the most populated metropolitan areas in Europe.

An important settlement for more than two millennia, Paris is today one of the world's leading business and cultural centres, and its influence in politics, education, entertainment, media, fashion, science and the arts all contribute to its status as one of the world's major global cities.

Paris and the Paris Region, with €533.6 billion in 2007, produces more than a quarter of the gross domestic product of France. According to 2007 estimates, the Paris urban agglomeration is Europe's second biggest city economy and the sixth largest in the world. The Paris Region hosts 38 of the Fortune Global 500 companies in several business districts, notably La Défense, the largest purpose-built business district in Europe. Paris also hosts many international organizations such as UNESCO, the Organisation for Economic Co-operation and Development, the International Chamber of Commerce and the informal Paris Club.

Paris is one of the most popular tourist destinations in the world, with 45 million tourists every year in the Paris Region, 60% of whom are foreign visitors. There are numerous iconic landmarks among its many attractions, along with world-famous institutions and popular parks.

The Métro is Paris' most important transportation system. The system, with 300 stations connected by 214 km of rails, comprises 16 lines, identified by numbers from 1 to 14, with two minor lines, 3bis and 7bis, so numbered because they used to be branches of their respective original lines, and only later became independent. In October 1998, the new line 14 was inaugurated after a 70-year hiatus in inaugurating fully new métro lines.

Because of the short distance between stations on the Métro network, lines were too slow to be extended further into the suburbs, as is the case in most other cities. As such, an additional express network, the RER, has been created since the 1960s to connect more-distant parts of the urban area. The RER consists in the integration of modern city-centre subway and pre-existing suburban rail. Nowadays, the RER network comprises five lines, 257 stops and 587 km of rails.
