Visiting Griffin in Mexico City I saw an amazing sculpture in the entrance of the vast courtyard of the National Museum of Anthropology. It is a monumental bronze piece, "El Paraguas" as it in known in Mexico is the sole support for a concrete roof that shades the entire vast patio and functions as a water feature. Besides the size what I love the most is the water cascades down from the top of the umbrella spokes instead of spraying up. Concrete, bronze and water I was in heaven.
