The Rosaire Chapel designed by Henri Matisse was polished throughout his last years. I visited this chapel located in Vance in my early 20's, and had a mysterious experience of being filled with overwhelming light and vibrant colors. A dream to build architecture like this chapel came up to me strongly. As one of the important elements in the architecture project “Rainbow Church”, the stained glass composed of 500 crystal prisms converts natural rays into rainbow color so that “miraculous light” appears in the space.
