Le Corbusier was an avowed atheist, but he also had a strong belief in the ability of architecture to create a sacred and spiritual environment. In the postwar years, he designed two important religious buildings; the chapel of Notre-Dame-du-Haut at Ronchamp (1950–1955); and the Convent of Sainte Marie de La Tourette (1953–1960). Le Corbusier wrote later that he was greatly aided in his religious architecture by a Dominican father, Père Couturier, who had founded a movement and review of modern religious art.
