An interior view of the Cathedral of Saint-Louis des Invalides looking from the nave towards the altar. Colossal Corinthian columns span the height of the nave and triforium arcades. The nave's ceiling is a groin vault. Flags line the nave where the vault meets the walls. On the left side of the image, a crucifix hangs from a colossal column, while the pulpit stands across the aisle from it.
