A street art festival in a disused water treatment plant in Val-de-Marne? This is the artistic and unusual event not to be missed this autumn in the Paris region. To be discovered over two days only, on Saturday October 5 and Sunday October 6, 2024, the "L'usine fait le mur" festival invites 21 street artists for a series of performances on the site of the former Saint-Maur-des-Fossés water treatment plant.
