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 as of 2014 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 as of 2014, and has its own regional council and president.
The centre of Paris contains the most visited monuments in the city, including the Notre Dame Cathedral and the Louvre as well as the Sainte-Chapelle; Les Invalides, where the tomb of Napoleon is located, and the Eiffel Tower are located on the Left Bank south-west of the centre. The banks of the Seine from the Pont de Sully to the Pont d'Iéna have been listed as a UNESCO World Heritage Site since 1991. Other landmarks are laid out east to west along the historic axis of Paris, which runs from the Louvre through the Tuileries Garden, the Luxor Column in the Place de la Concorde, the Arc de Triomphe, to the Grande Arche of La Défense.
