Seclin’s Fête des Harengs places a humble Northern food symbol at the centre of a town celebration. The 2026 programme links music, flavours, craft stalls, family activities and a parade between the Hôtel de Ville and the Collégiale Saint-Piat. The presence of local giants gives the day a clear Hauts-de-France identity, joining food, civic procession and popular folklore in one route. It is a festival of public squares and shared memory, where herring becomes a simple but effective sign of local belonging.
