When you visit Sagrada Familia by Antoni Gaudi, it is easy to overlook minor details overwhelmed as you are by the emotional impact of this gigantic masterpiece of universal architecture. When in front of the Nativity Façade, which you can better appreciate sitting on the exterior wall of the premises, take a good look at this floral adornment at one side of the iron gates, notice the elaborate and incredibly realistic contour of the kelp-like metal work. I have to say that this is not the authentic color, of course. Check original picture here.
