Frederick R. Weisman Art Museum, Minneapolis

Frederick R. Weisman Art Museum's mostly 20th-century collection contains the world's largest assemblage of works by Marsden Hartley and Alfred Maurer, as well as paintings and prints by Georgia O'Keefe, Arthur Dove and Robert Motherwell. However, many critics consider the building itself to be a stunning piece of art. Designed by Frank Gehry, the flamboyant 1993 building is possibly the most talked-about structure in the Twin Cities. The museum's collections are displayed in galleries the New York Times has referred to as possibly the five best rooms for art viewing in the world. Admission is free.
