Sagrada Familia's fractal qualities allow more light into its famed stained glass windows.
Sagrada Familia in Barcelona, designed by Antoni Gaudi. He studied how plants grow and noticed patterns and fractals. He considered all this when he built this cathedral in a way to maximize light. Compared to this modernist Gothic cathedral, 15th century Gothic cathedrals had nowhere as much light come through. He maximized by using geometry and included fractal structures -- a stem that splits up and splits again -- one of the most beautiful man-made fractals.
