Art Institute of Chicago

DOWNTOWN. A highlight of any trip to Chicago, this museum is home to one of the best and most diverse art collections in the world. People are drawn first to the vast Impressionist collection, including the world's largest group of Monet paintings. But treasures abound, including the haunting "American Gothic" and Seurat's groundbreaking Pointillist work. The contemporary section has been expanded and now includes pieces by Picasso, Matisse, Dali, Pollock, and Warhol. The temporary shows are also well known and always receive critical acclaim. A recent retrospective focused on the life and works of Van Gogh.
