The site is high on a hill near Belfort in eastern France. There had been a pilgrimage chapel on the site dedicated to the Virgin Mary, but it was destroyed during the Second World War. After the war, it was decided to rebuild on the same site, The new chapel was built for a reformist Church looking to continue its relevance. Warning against decadence, reformers within the Church at the time looked to renew its spirit by embracing modern art and architecture as representative concepts. Father Marie-Alain Couturier, who would also sponsor Le Corbusier for the La Tourette commission, steered the unorthodox project to completion in 1954.
