The Church of Notre-Dame du Raincy is a modern church built between 1922-23 by the French architects Auguste and Gustave Perret.
It is sometimes called the “Holy Chapel of Reinforced Concrete,” and it has the peculiar particularity of being the first place of worship built in France using grey cement.
Le Corbusier was Auguste Perret’s assistant, who then became the Pygmalion of modern architecture. He used to say, “Le Raincy wears a mask, a façade that hides the beauty of the vessel.”
