 It was Father Couturier who brought Bazaine into the project for the Church of the Sacred Heart at Audincourt (1951), where this time Fernand Léger was to design the stained glass (executed by Jean Barillet); to Bazaine fell the mosaic for the outside wall.Later (1954) he also completed the glazed wall of the baptistery.The Eglise de Sacré-Cœur d'Audincourt, built in part with the savings of the industrial workers who composed the parish—and who chose the avowed "communist" Fernand Léger as their creative (and extremely versatile) main interpreter—stands as one of the great monuments of twentieth-century "sacred art".
