The Marché du Boulingrin is retained as a Reims heritage-and-market tradition, not as a gastronomy category item. It takes place inside the Halles du Boulingrin, a landmark covered hall inaugurated in 1929 and now inseparable from the city’s public identity. The stalls matter because they keep a local rhythm of producers, food artisans and residents alive inside a listed modernist building. For publication, the emphasis is the living use of a historic hall: visitors encounter Reims through architecture, everyday market culture and the social memory of a place that still belongs to the city.
