Biennial medieval reenactment in the heart of the historic town of Tonnerre in Burgundy
Les Médiévales de Tonnerre plunges the Burgundian town of Tonnerre into the atmosphere of the Middle Ages for a weekend in September. Knights in armor, troubadours, jugglers, and craftspeople take over the cobbled streets and the Place Marguerite-de-Bourgogne. A large medieval market, jousting, equestrian shows, and a lavish banquet in the 13th-century Hôtel-Dieu make this biennial festival one of the unmissable historical events in the Yonne region.
Every two years, in September, the town of Tonnerre (Yonne) transforms into a true medieval city for an exceptional weekend. The Médiévales de Tonnerre is the unmissable event for history and historical reenactment enthusiasts in Burgundy, bringing together several thousand visitors in a remarkable heritage setting.
The setting of Tonnerre lends itself naturally to this evocation of the past. The Hôtel-Dieu, built in the 13th century by Marguerite de Bourgogne, serves as the exceptional backdrop for the event. Its Gothic halls host a gastronomic medieval banquet, while its surroundings are adorned with banners, flags, and period armor. The main streets of the town, the Place Marguerite-de-Bourgogne, and the Pâtis are populated by characters in period costume: knights, soldiers, peasants, monks, musicians, washerwomen, and merchants.
The program of the Médiévales offers a complete immersion into medieval life:
Organized by the association Les Médiévales de Tonnerre, these days benefit from the support of the town and the community of communes Le Tonnerrois en Bourgogne. The event mobilizes hundreds of volunteers and welcomes troupes from all over France and sometimes Europe. Its biennial nature gives it an exceptional character that builds a loyal audience, often exceeding 10,000 visitors over the weekend.
The town of Tonnerre itself is a remarkable heritage site. Its Hôtel-Dieu, classified as a Historic Monument, is one of the finest examples of medieval hospital architecture in France. The town is also known for its vineyard (AOC Épineuil), its Fosse Dionne, a Vauclusian spring with deep blue waters, and its rich historical past linked to the Dukes of Burgundy.
Les Médiévales de Tonnerre return in September 2026 for a new biennial edition in the exceptional historic setting of the town of Tonnerre. Knights, troubadours, a medieval market, equestrian shows, and a banquet in the 13th-century Hôtel-Dieu will allow the public to fully immerse themselves in the Burgundian Middle Ages.
In September 2026, the Médiévales de Tonnerre are preparing to reconquer the streets and squares of the Burgundian town for a new, highly anticipated biennial edition. The event will once again bring together hundreds of reenactors, artisans, and artists to dress Tonnerre in medieval colors.
On the program: medieval market with craftspeople, equestrian shows and jousting, troubadour and minstrel entertainment, old games for children, and, the highlight of the event, the gastronomic medieval banquet in the Gothic hall of the 13th-century Hôtel-Dieu. The detailed program will be published in spring 2026 on the social media channels of the organizing association.
