This Journées Européennes du Patrimoine listing is retained because the official Culture page confirms a free, on-site conference at the Camp de la Transportation during the 19-20 September 2026 heritage weekend. The subject is directly connected to Saint-Laurent-du-Maroni’s identity as a Ville d’Art et d’Histoire: the renewal of the label and the future of heritage mediation. The event is valuable for publication because it links public participation, urban memory and long-term cultural policy.
