Sunday, Trinity Day, marks the most significant day of the Ducasse festival in Mons, following the initiation of festive celebrations on Friday evening with popular concerts at Mons’ Grand Place.
The Sunday festivities will start with the traditional Procession at 9:30, where approximately 1,600 participants in period costumes will parade from Sainte-Waudru Ramp through the heart of the Doudou city, leading up to the “Montée du Car d’Or”. Over 60 groups representing various confraternities and parishes of Mons, along with two invited groups—the Guild and a delegation from the Maubeuge Procession—will join, supported by scores of musicians and choristers.
The highlight of the Ducasse ritual will be the “Combat dit Lumeçon”, a symbolic battle between the hero, Saint George, and the Dragon, signifying the struggle between good and evil. This event will take place at 12:30 at the Grand Place. Recognised by UNESCO since 25 November 2005 as Intangible Cultural Heritage of Humanity, the Ducasse ritual of Mons is deeply cherished.
Celebrations of the Mons Ducasse will continue for much of the week, including a “Doudou Sound Party” on 16 June at 20:30, a street fanfares festival, and a mega flea market. The festivities will conclude with the “Petit Lumeçon”, a child-oriented reenactment of the Saint George and Dragon Combat, on 22 June at 12:30 at the Grand Place. This will be followed by the “Remontée de la Châsse” at 18:00 pm at the Sainte-Waudru Collegiate, marking the finale of the 2025 schedule.
