Six new audio-guide terminals are being inaugurated this year in the downtown and Villaroy neighbourhoods, in collaboration with Flashback. Installed in front of the swimming pool, the Gogottes garden, or the Ernest-Defay square, they will allow you to listen to the history of the place by flashing a QR-code with your smartphone. You will be given a plan to discover them all. For children from 8 years old, the course is offered in the form of a track game: the young Archibald Piedefer wants to discover the secret of his family, come and help him! Distribution of plans and books of the game of track between 3 pm and 4:30 pm. Smartphone indispensable.
