What Is the Doudou?

Every year on Trinity Sunday (the Sunday after Pentecost, usually falling in late May or early June), the city of Mons erupts into one of the most extraordinary festivals in Europe. Known officially as the Ducasse de Mons and affectionately as the Doudou by locals, this event draws tens of thousands of visitors and has been inscribed on UNESCO's List of Intangible Cultural Heritage of Humanity since 2005.

The festival is not a re-enactment or a tourist performance — it is a living tradition that has been celebrated in Mons since at least the 14th century, and locals take it with complete seriousness and enormous civic pride.

The Two Central Rituals

1. The Procession of the Car d'Or

The day begins with the solemn religious procession of the Car d'Or (the Golden Carriage). This magnificent baroque carriage carries the châsse (reliquary) of Saint Waudru, patron saint of Mons, through the streets of the city. The carriage is pulled by a team of white horses and escorted by costumed guilds, soldiers, and religious figures in a procession that winds through the historic centre.

The ceremony has a deeply superstitious element: according to tradition, if the Car d'Or successfully makes it up the steep cobblestone ramp to the Collegiate Church of Sainte-Waudru without the horses faltering, the coming year will be prosperous for Mons. When it succeeds, the crowd erupts in celebration; if it struggles, unease spreads through the city.

2. The Lumeçon — Combat of Saint George and the Dragon

The afternoon brings the most theatrical and visceral part of the Doudou: the Lumeçon. In the Grand-Place, a large crowd forms a ring as Saint George (the Gilles) battles a giant papier-mâché dragon known as the Doudou — which gives the whole festival its nickname.

The dragon is carried and operated by a team of men dressed in white, called the chin-chin, who wield the dragon's long tail like a whip. Spectators rush in to try to grab a hair from the dragon's tail — a feat believed to bring good luck for the year ahead. The dragon periodically knocks back the crowd, creating a thrilling, somewhat chaotic atmosphere.

After a prolonged battle, Saint George finally slays the dragon to the wild cheers of the assembled Montois. The entire sequence is accompanied by traditional music played by local musicians.

Practical Information for Visitors

The Musée du Doudou

For those visiting outside festival time, or who want to understand the tradition in greater depth, the Musée du Doudou in Mons provides an excellent interactive exploration of the festival's history, symbolism, and costumes. It's a worthwhile visit at any time of year.

A Festival Unlike Any Other

The Doudou is proof that Mons is far more than just a stop between Brussels and Paris. It is a city with deep roots, fierce local pride, and a capacity for collective joy that few places in Europe can match. If you can time your visit to coincide with the festival, do it — it is an experience you will not forget.
