Each year, the Journées de l'Archéologie invites both young and old to explore the past in an unconventional way, through gestures, objects, traces and discoveries. In 2026, the event runs from June 12 to 14. In Argenteuil, this gathering finds a particularly inspiring setting with L’Atelier, Jardins de l’Abbaye.
Here you discover both the remains of the Notre-Dame Abbey, revealed by archaeological excavations carried out since 1989, including traces of a crypt, a chapter house, a cloister and a necropolis, but also an old building linked to the site’s industrial history, today repurposed as a cultural space. In other words, you’re not just visiting a heritage site: you’re walking through a slice of urban history where the Middle Ages, archaeology, landscapes and industrial memory resonate with real charm.
