Île-de-France, in northern France, orbits Paris—the City of Light—as its capital, a global icon of art, fashion, and the Eiffel Tower amid a sprawl of history and suburbs. Known for croissants, Versailles, and a cultural heft, its economy dominates with finance, tech, and tourism, blending medieval roots with modernity. Its Seine banks and chic streets dazzle. Île-de-France’s elegance reigns.
