The Musée de l'Air et de l'Espace fills the old Le Bourget airport with aircraft, rockets, satellites, and the kind of engineering that makes aviation history feel physical. It is one of the oldest air and space museums in the world, and the setting matters: Le Bourget was an important airfield long before Paris had its modern airports.
The space displays are the main draw for many visitors, with rocket models, satellites, and a planetarium. Families should also look for Planète Pilote, an interactive area aimed at younger children, while aviation fans can spend much longer working through the hangars.
