La Défense is a major business district of the Paris aire urbaine. With a population of 20,000, it is centered in an orbital motorway straddling the Hauts-de-Seine département municipalities of Nanterre, Courbevoie, and Puteaux. The district is at the westernmost extremity of Paris’s 10 km long Historical Axis, which starts at the Louvre in Central Paris and continues along the Champs-Élysées, well beyond the Arc de Triomphe before culminating at La Défense.
