Paris, the cosmopolitan capital of France, is one of the largest agglomerations in Europe, with 2.2 million people living in the dense (105 km²) central city, 7 million people in the Metropole du Grand Paris (814 km²) and almost 12 million people living in the metropolitan area. In the north of the country on the river Seine, Paris has the reputation of being the most beautiful and romantic of all cities, brimming with historic associations and remaining vastly influential in the realms of culture, art, fashion, food and design. Dubbed the City of Light (la Ville Lumière) and Capital of Fashion, it is home to some of the world's finest and most luxurious fashion designers and cosmetics, such as Chanel, Christian Dior, Yves Saint-Laurent, Guerlain, Lancôme, L'Oréal, and Clarins. A large part of the city, including the banks of the Seine, is a UNESCO World Heritage Site. The city has the second highest number of Michelin-starred restaurants in the world (after Tokyo) and contains numerous iconic landmarks such as the Eiffel Tower, the Arc de Triomphe, Notre-Dame de Paris, the Louvre, the Moulin Rouge and the Basilique du Sacré Cœur, making it one of the most popular international tourist destinations in the world, with around 14 million tourists annually.
The city of Paris itself is officially divided into 20 districts called arrondissements, numbered from 1 to 20 in a clockwise spiral from the centre of the city (which is known as Kilomètre Zéro and is located at the front of Notre Dame). Arrondissements are named according to their number. You might, for example, stay in the "5th", which would be written as 5e in French. The 12th and 16th arrondissements include large suburban parks, the Bois de Vincennes, and the Bois de Boulogne respectively.
