Every year, the Journées du Patrimoine invites the public to discover places that bring the region's heritage to life, from historic monuments to industrial sites or infrastructure that are typically off the beaten path. In the Val-d'Oise, the aérodrome de Pontoise-Cormeilles-en-Vexin is among the places that will open their doors for a special occasion. The 19 and 20 September 2026, this event will be waiting for you across the Île-de-France.
Established in 1937, the airfield has lived through several lives. Initially used by the French military, it was occupied during World War II by German forces, who built concrete runways and several buildings there. After liberation, the site gradually returned to aviation activity before opening to public air traffic. Today, it is operated by the Groupe ADP and stands as one of the region’s major general-aviation airports.
The airfield welcomes thousands of movements each year, ranging from business jets to leisure aircraft and training aircraft. It also plays a key role in pilot training, aircraft maintenance, and civil-protection missions. A hub where aviation professionals, trainee pilots, mechanics, and aviation enthusiasts cross paths every day.
Beyond its present function, the site still bears marks of its past. Nearby the old air terminal lies a hangar built during the Occupation, its walls scarred by bullet and shell holes. A stark reminder that the aerodrome’s history is inseparable from the region’s story in World War II.
