Antoni Gaudí, 1852-1926, was the Spanish architect of the world's longest currently running architectural projects. Gaudí evokes, through advanced engineering & design elements, the feeling of a quiet forest with light streaming in, and using geometric organic elements, such as the spiral of a snail shell, the hexagonal pattern of a bee hive, and the straight line on a curved leaf, the spiritual beauty of Nature. Estimated completion 2026.
