Do not hesitate to cross the door of the municipal archives! Housed under the Media Library of the city center, this public service of communal archives enriched with private archives ensures the dissemination of the documentary heritage of Argenteuil. From the first ostensions of the relic of the Holy Tunic to the two great conflicts of the twentieth century, we discover more than eight centuries of historical events, landscape evolution, personalities of the small as the great history. L'Archi-Mur: for the little visitors, a decorative mural with chalk will give free rein to their imagination around the theme of the poppy!
