The oldest fair in France, since 1219
Founded in 1219, the Beaucroissant Fair is the oldest fair in France. Every year in September, this unmissable event for the agricultural world covers over 30 hectares and 15 km of aisles in Beaucroissant, Isère. With over 1,500 exhibitors, 700 head of livestock, 80 bars and restaurants, a funfair, and a huge market, the fair attracts nearly 300,000 visitors over three days. Free admission.
The Beaucroissant Fair is an exceptional event whose origins date back to 1219, making it the oldest fair in France still in operation. Its history is intimately linked to a founding tragedy: on the night of September 14, 1219, the natural lake of Saint-Laurent, held back by a landslide in the gorges of l'Infernet, suddenly gave way. The devastating wave submerged Grenoble and caused the death of nearly 5,000 people. The following year, on September 14, 1220, under the leadership of the Bishop of Grenoble, the survivors commemorated the catastrophe by making a pilgrimage to Parménie, the bishops' residence perched at an altitude of 749 meters. The gathering attracted such a crowd that a village was formed to accommodate them, and merchants naturally flocked: the Beaucroissant fair was born.
Medieval chroniclers mention gatherings prior to 1219, dating back to the construction of the Parménie chapel in 877. As early as 977, Bishop Isarne organized a "vaude" (fair) to commemorate his victory over the barbarians, every September 14, the day of the Feast of the Holy Cross. In 1836, King Louis-Philippe I authorized by ordinance a second fair in the spring, thus creating the double tradition that continues to this day.
The September fair is the larger of the two annual editions. It covers over 30 hectares, equivalent to 42 football fields, with 15 kilometers of aisles to explore. More than 1,500 exhibitors gather there, including about 220 professionals in agricultural and public works machinery, who present the latest innovations in tractors, harvesting machines, livestock equipment, and forestry equipment. The market fair brings together over 700 traders offering food, crafts, tools, housing, furniture, automobiles, and many other sectors.
True to its agricultural vocation, the Beaucroissant Fair traditionally hosts nearly 700 head of livestock on Friday, the day dedicated to breeders. Cattle, horses, sheep, and goats are presented by breeders from the Auvergne-Rhône-Alpes region. Animal competitions and presentations highlight the expertise of breeders from Isère and neighboring departments.
The dog fair brings together about twenty breeders presenting various breeds, while the poultry and small animal sector gathers more than 50 exhibitors. Lovers of local breeds, ornamental chickens, rabbits, and birds will find a wide selection here. These areas delight families and animal lovers.
A large funfair with about 70 attractions (rides, games) accompanies the fair from 10 am to midnight. With 80 bars and restaurants spread across the entire site, there is no shortage of food: Isère specialties, grills, local Dauphiné products, and a festive atmosphere are available from 8:30 am to 11 pm. The Beaucroissant Fair is more than just a commercial event: it is a true popular festival that brings together all generations.
The 805th edition of the Beaucroissant Fair will be held from September 11 to 13, 2026. An unmissable event for the agricultural world in Isère, the oldest fair in France will once again bring together over 1,500 exhibitors, agricultural machinery, a huge market fair, livestock, a funfair, and 80 bars and restaurants on 30 hectares.
The 805th edition of the Beaucroissant Fair will take place from Friday, September 11 to Sunday, September 13, 2026, on the Beaucroissant fairgrounds in Isère. Eight centuries after its creation, the oldest fair in France continues to bring together farmers, breeders, traders, and visitors in a spirit of conviviality and tradition.
