Le Mesnil-Saint-Denis Twinning Committee Flea Market

A flea market in a château-town hall, a heritage rarity

Some flea markets stand out for their exceptional setting, but few can claim to take over the inner courtyard of a genuine château transformed into a town hall. That is the privilege of the one organised each spring by Le Mesnil-Saint-Denis Twinning Committee. Exhibitors set up their stalls within the historic grounds of the municipal building.

A late May Sunday in a historic setting

The event is held on Sunday 24 May 2026, from 9 AM to 5 PM, with setup from 7 AM. This generous timeframe allows visitors to come at their convenience.
