The section of Le Corbusier’s well-known pilgrimage chapels reveals material and structural paradoxes. Both the south wall and the roof appear to be massive but are hollow. The ceiling, over 7 ft (2.1 m) deep in some areas, is formed by curved concrete girders and parallel purlins that span between the girders. This structural system produces the convex underbelly defining the interior of the church and gathers into a single rain scupper at the rear.

Following the topography of the site, the floor slopes gently toward the altar. Unlike those religious spaces that use a concave ceiling to gather and focus an interior space, the convex, shaped section of Ronchamp pushes against the periphery, while merging with three smaller chapels at the sides of the nave.
