Solomon R. Guggenheim Museum
Perhaps best known for its winding spiral ramp structure, the Guggenheim's walls are adorned with some of the most important modern and contemporary art of the 20th and 21st centuries. The building was designed by Frank Lloyd Wright, one of the most prominent architects in American history, with works by Kandinsky, Picasso, Chagall, and many more artists. Be sure to check out their exhibit on Italian Futurism - it will be gone in September!
