Origin and history

The church of Saint-Oyen de Meillonnas, located in the Ain department in the Auvergne-Rhône-Alpes region, finds its origins in the Middle Ages, with a first mention of the parish around 1080. The present building, partly medieval, underwent major reconstructions in the 17th and 19th centuries, especially between 1832 and 1840. These works incorporated ancient elements, such as the chapels of John of Corgenon (or Notre-Dame) and the Holy Spirit, decorated with 14th-century frescoes rediscovered in 1986 and partially opened in 1997.

The Notre Dame chapel, surmounted by a bell tower around 1840, lost its original east wall, pierced by a Gothic bay, replaced by a large arcade in the 19th century. The frescoes, partially visible through soundings, suggest a wider wall decor, now partly masked. The church, classified as a historical monument in 2002, thus illustrates a superimposition of styles and periods, from medieval frescoes to 19th century developments.

The church of Saint-Oyen, owned by the municipality of Meillonnas, bears witness to the local architectural and religious evolution. Its classification in 2002 highlights its heritage value, combining Gothic heritage, Baroque transformations and 19th century interventions. The 14th century frescoes, though fragmentary, offer a rare glimpse of medieval wall decoration in the region, while the restoration campaigns have adapted the building to successive cultural and aesthetic needs.
