The presence of architecture in La Tourette is found in the contrasting uses of light employed by Le Corbusier, in which light plays two distinct roles. First, light is used as a planar condition along the primary axis. In contrast to the planar condition, spaces on the transverse axis use light as a dynamic element, flooding the space with figurative light. The variation of apertures around the structure create dynamic conditions inside the space.
The diagrams explore the ideas of hierarchy, proportion, and asymmetry in the chapel. The most prevalent in the space is proportion. While the plan follows a loose proportional structure, the short section of the chapel follows a rigid method of golden rectangle and square proportions.
