The chapel of Saint-Prix is located on the border of the communes of Dyo and Saint-Symphorien-des-Bois. According to a charter of the cartulary of Cluny, it would have been founded in the 11th century, next to a fountain whose water quality is renowned. It seems to be the oldest place of worship in the parish of Dyo.
