At the top of Museum Mile you cannot miss the dramatic Solomon R. Guggenheim Museum of Art housed inside Frank Lloyd Wright's masterpiece of a giant nautilus shell. A monument to modernism, the unique architecture of the space, with its spiral ramp riding to a domed skylight thrills visitors. In the words of Paul Goldberger, "Wright's building made it socially and culturally acceptable for an architect to design a highly expressive, intensely personal museum. In this sense almost every museum of our time is a child of the Guggenheim." Examples of exhibits include masterpieces by Marcel Duchamp, Max Ernst, Picasso, and works by Jackson Pollock.
