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