During the Second World War, the German army chose this remote site to train its aircraft pilots. It was to house the devices that an immense concrete dome was built, which still stands solid as rock today in the Chesnay woods.

The Bois du Chesnay arch

Highlight • Natural

In the Chênais Forest, near Vétheuil, don't miss this impressive old concrete dome. Built by the German army during World War II, it was used to conceal fighter planes from Allied aircraft. A place steeped in history, discreet but fascinating, nestled in the heart of nature.
