Portland Museum of Art The Portland Museum of Art, founded in 1882, is Maine's oldest and largest public art institution. The Museum's three architecturally significant buildings unite three centuries that showcase the history of American art and culture. With more than 17,000 objects, the Museum's collection includes decorative and fine arts dating from the 18th century to the present. The heart of the Museum's collection is the State of Maine Collection, which features works by artists such as Winslow Homer, Marsden Hartley, John Marin, Louise Nevelson, and the Wyeth family. The Museum has the largest European collection in Maine. The major European movements from Impressionism through Surrealism are represented by works by Mary Cassatt, Edgar Degas, Claude Monet, Pablo Picasso, and Pierre-Auguste Renoir. In addition to exhibitions, the Museum offers a host of dynamic educational programs for all ages including family festivals, films, lectures, art classes, and musical performances.
