The town of Joinville-le-Pont, in the Val-de-Marne region of France, is getting ready to unveil a new cultural, artistic, nature and family site, called LE SPOT. The idea? Transform the "abandoned" area of the A4 freeway into an open-air gallery, urban forest and sports venue. We tell you more about this project, due for completion in spring 2025, in the south-east of the Paris region.
