The design is graphic and feels so contemporary. It took my breath away, over and over. Something so deceptively simple and so careful, and stunning in its composition and its use of white. Five or six or seven colors, with different veining and pattern. This is still the Benedictine church, and we saw it repeated in many varieties everywhere we went. This one is a special favorite, though!
