Brocante Fête des harengs de Mainneville - October

Review of the Mainneville Flea Market and Fête des harengs - October 2025

In October 2025, Mainneville held its annual popular festival combining a flea market and the Fête des harengs. The Norman village came alive for an autumn day, bringing together flea market enthusiasts and food lovers around stands of grilled and marinated herring and flea market stalls.

This original combination of popular Norman gastronomy and a flea market charmed visitors from all over the Vexin and surrounding areas. The conviviality of the festival, the smell of grilled herring, and the October atmosphere in this preserved village of the Vexin normand contributed to the success of this event. Next meeting in October 2026.
