What makes this church surprising is the touch of multicolored light projected through the concrete patterns covered with colored glass. Totally unexpected as a source of light compared to the usual stained glass, these geometric shapes produce an amazing lighting when the sun hits them. Along with the strong concrete pillars on which the tower seems to hold, the patterns of holes give the building its unexpected personality. Again I find them extremely difficult to photograph, since they are so fugitive, depending on the sun and the clouds. They can disappear totally and then suddenly illuminate the heart of the church in a kind of miraculous atmosphere. Mr Auguste Perret was very inspired when he designed this church.
