Complexe Leonard de Vinci

Every summer since 1990, footballers without a club have gathered here. The UNFP FC camp has made the Complexe Léonard de Vinci one of the few grounds in French football known for who trains on it rather than who plays there.

That tells you most of what the place is. The complex sits in the Essonne, south of Paris, and combines pitches with a hotel and seminar rooms — a working base rather than a venue. Squads eat, sleep and train inside the same perimeter, which is why national teams passing through the Paris region use it: the Guinea national side has been among them.
