Vallée-des-Rivières was incorporated on January 1, 2023 via the amalgamation of the former town of Saint-Léonard and the former village of Sainte-Anne-de Madawaska as well as the concurrent annexation of adjacent unincorporated areas.

[citation needed] It is located 30 km south east of Edmundston on the east bank of the Saint John River opposite Van Buren, Maine, to which it is connected via the Saint Leonard–Van Buren Bridge.

[5] Located on Principale Street, the village's place of worship was built in 1923, featuring St. Anne on the top of the establishment.

Its location is based in the middle of the village on its highest promontory, reflecting the importance of the Roman Catholic religion in the parish.

The church, which is made of local granite, features a Latin cross layout and has a broad central nave and narrow transepts.
