Charles de Gaulle International Airport — Paris (Roissy-en-France, Val-d'Oise), France

Charles de Gaulle International Airport opened north of Paris in 1974 near the town of Roissy-en-France, taking its name from the wartime general and postwar president who shaped modern France, and it has since grown into one of the world's busiest air hubs and the primary home base for Air France and the SkyTeam alliance. Architect Paul Andreu's original circular Terminal 1, with its tube-shaped passenger walkways radiating outward, became an instantly recognizable symbol of 1970s futurist design, though the airport's later Terminal 2E suffered a partial ceiling collapse in 2004 that killed several people and forced a significant safety review of the structure's design. Today CDG sprawls across multiple terminals linked by an automated people-mover and connected to central Paris via a dedicated RER commuter rail line, handling tens of millions of passengers annually alongside substantial cargo operations. Its parallel runway system allows simultaneous operations even in poor visibility, a critical feature given the airport's role as a long-haul connecting point between Europe, Africa, the Americas, and Asia.
