Paris-France

Paris is the capital city of France. It is situated on the River Seine, in northern France, at the heart of the Île-de-France region ("Région parisienne"). Paris has an estimated population of 2,153,600 within city limit (2005 est.). The Paris urban area has a population of 9.93 million and a commuter belt around the same completes the Paris "aire urbaine" (roughly: "metropolitan area") that, with its population of 12 million, is one of the most populated areas of its kind in Europe.
Paris' location at a crossroads between land and river trade routes in lands of abundant agriculture had made it one of France's principal cities by the 10th century, rich with royal palaces, wealthy abbeys and a cathedral; by the 12th century Paris had become one of Europe's foremost centres of learning and the arts. Today, Paris is a major influence in politics, fashion, business, arts and science. The city serves as an important hub of intercontinental transportation and is home to universities, sport events, opera companies and museums of international renown, making it an attraction for over 30 million foreign visitors per year.
The Paris region (Île-de-France) is France's foremost centre of economic activity. With €478.7 billion (US$595.3 billion), it produced more than a quarter of the gross domestic product (GDP) of France in 2005. With La Défense, the largest purpose-built business district in Europe, it hosts the head offices of almost half of the major French companies, as well as the headquarters of ten of the world's 100 largest companies. Paris also hosts many international organizations such as UNESCO, the OECD, the ICC, or the informal Paris Club.

Geography
Paris is located on a north-bending arc of the river Seine and includes two islands, the Île Saint-Louis and the larger Île de la Cité which forms the oldest part of the city. Paris has several prominent hills, of which the highest is Montmartre at 130 metres (426 ft) above sea level.
Paris, excluding the outlying parks of Bois de Boulogne and Bois de Vincennes, covers an oval measuring 86.928 square kilometres (33.56 mi²) in area. The city's last major annexation of outlying territories in 1860 not only gave it its modern form, but created the twenty clockwise-spiralling arrondissements (municipal boroughs). From its 1860 78 km² (30.1 mi²), these limits expanded marginally to 86.9 km² in the 1920s, and in 1929 the Bois de Boulogne and Bois de Vincennes forest parks were officially annexed to the city, bringing its area to its present 105.397 square kilometres (40.69 mi²).
The Paris metropolitan area extends far beyond the city limits, forming an irregular oval with arms of urban growth extending along the Seine and Marne rivers from the city's south-east and east, and along the Seine and Oise rivers to the city's north-west and north. Further, beyond the central suburbs, population density drops sharply in the surrounding land; a mix of forest and agriculture dotted with a network of relatively evenly dispersed satellite towns, this commuter belt, when combined with the Paris agglomeration, completes a Paris aire urbaine (metropolitan area) that covers an oval 14,518 km² (5,605.5 mi²)[citation needed] in area, or about 138 times that of Paris itself.


Cityscape
"Modern" Paris is the result of a vast mid-19th-century urban remodelling. For centuries it had been a labyrinth of narrow streets and half-timber houses, but beginning in 1852, the Baron Haussmann's vast urbanisation levelled entire quarters to make way for wide avenues lined with neo-classical stone buildings of bourgeoise standing; most of this 'new' Paris is the Paris we see today. These Second Empire plans are in many cases still actual, as the city of Paris imposes the then-defined "alignement" law (imposed position defining a predetermined street width) on many new constructions. A building's height was also defined according to the width of the street it lines, and Paris' building code has seen few changes since the mid-19th century to allow for higher constructions. It is for this reason that Paris is mainly a "flat" city.
Paris' unchanging borders, strict building codes and lack of developable land have together contributed in creating a phenomenon called muséification (or "museumification") as, at the same time as they strive to preserve Paris' historical past, existing laws make it difficult to create within city limits the larger buildings and utilities needed for a growing population. Many of Paris' institutions and economic infrastructure are already located in, or are planning on moving to, the suburbs. The financial (La Défense) business district, the main food wholesale market (Rungis), major renowned schools (École Polytechnique, HEC, ESSEC, INSEAD, etc.), world famous research laboratories (in Saclay or Évry), the largest sport stadium (Stade de France), and some ministries (namely the Ministry of Transportation) are located outside of the city of Paris. The National Archives of France are due to relocate to the northern suburbs before 2010.
