Undeclared open-air garages have been thriving in the car parks of Grigny (Essonne) for a long time. For years, the authorities have been fighting against ‘wild’ (or illegal) garages, set up in the open air in car parks.

“A real scourge,” says the town hall. The scene is usual in one of the poorest towns in Essonne, where more than 17,000 inhabitants live together.
