The new church of Saint-Honoré-d'Eylau was built in 1896. The building was first used as a catechism chapel. In 1974, the chapel became a parish church and received its current name. The architect Paul Marbeau (1843-1907), influenced by the 1889 World's Fair, used an iron metal structure. This allowed it to combine the speed of construction, its solidity, low cost and space. He chose to leave this structure visible. The style of the building joins the neo-Gothic (especially by the presence of white butt arches clearly visible under the vault). The façade is inspired by the roman style. Saint-Honoré-d'Eylau is characterized by its architectural lightness and its space that the eye can embrace with a single glance (thanks to thin metal pillars that do not break the view). Quite poor in ornamentation, the church nevertheless has a very rich collection of Art Deco glass windows. After Vatican Council II, the architect André le Donné made changes to it, notably at the level of the choir and a recent restoration gives it an elegance very conducive to contemplation.
