2026 Edition
The patronal festival of Perreuse takes place on Sunday, September 6, 2026, following the tradition of the first Sunday in September as noted by the commune of Treigny-Perreuse-Sainte-Colombe. It is organized by the Comité des villages en fête, an association based at the town hall square in Treigny.
The flea market will occupy the fairground on Rue de la Chaume in Perreuse from 7:00 AM to 5:00 PM. The organizers expect 75 exhibitors for this 32nd annual event. The market is held outdoors with no reservations required; exhibitor setup begins at 6:00 AM. The first 2 meters are free, with each additional meter costing €2; food vendors are not permitted. Refreshments, food, and restrooms are available on-site.
The festival is named after Saint Mammès, to whom the church in Perreuse is dedicated. The building features a 12th-century Romanesque choir and a 16th-century Renaissance nave. Its wall paintings, discovered in 1997, make it a key stop on the Puisaye mural circuit. Sacked by the Huguenots in 1587, the church received a donation in 1667 from the Grande Demoiselle, granddaughter of Henri IV and Baroness of Perreuse. Its stained glass windows are currently the subject of a Fondation du patrimoine fundraising campaign. The organizers have not announced any church openings for the day of the festival.

Saint-Mammès, the patronal festival of Perreuse
The Fête de la Saint-Mammès is the patronal festival of Perreuse, a village within the municipality of Treigny-Perreuse-Sainte-Colombe, located in the western part of the Yonne department in the Puisaye region. The municipality holds the event on the first Sunday of September, organized by the 'Comité des villages en fête' association, based at the town hall square in Treigny.
The day centers around an open-air flea market set up on the fairgrounds on Rue de la Chaume. The organizers expect 75 exhibitors, and the event runs from 7:00 AM to 5:00 PM, with entertainment, refreshments, food, and restrooms available on-site. Exhibitors can set up starting at 6:00 AM, with no reservation required.
The Church of Saint-Mammès in Perreuse
The festival takes its name from the village church, dedicated to Saint Mammès. The building combines a 12th-century Romanesque choir with a 16th-century Renaissance nave. Mural paintings discovered there in 1997 led to its inclusion in the Puisaye mural painting circuit.
Sacked by the Huguenots in 1587 during the Wars of Religion, the church fell into disrepair until the 17th century. In 1667, it received a significant donation from the 'Grande Demoiselle', granddaughter of Henri IV, cousin of Louis XIV, and Baroness of Perreuse. Its stained-glass windows, now broken or missing, allow moisture to enter and damage the walls; the municipality is currently running a fundraising campaign with the Fondation du patrimoine to restore them.
The three villages and the Puisaye region
The municipality encompasses Treigny, Perreuse, and Sainte-Colombe. Treigny is a village of potters: the Association of Puisaye Potter Creators exhibits at 'Le Couvent', and the Potters' Market is held there on the second Sunday of August. The Château de Ratilly and the Guédelon medieval construction site are also located within the municipal territory.
Other events announced by the municipality include the 'Foire du Renouveau' (second Sunday of March), the Treigny flea market (early July), the July 13th and 14th festivities, the Saint-Hubert beer festival in Sainte-Colombe (first Sunday of August), the Pumpkin Festival in Sainte-Colombe (late October), and the Treigny Advent Market (third weekend of November).
