Founded in 1882, this well-respected museum houses an outstanding collection of American artists. Maine artists, including Winslow Homer, Edward Hopper, Louise Nevelson and Andrew Wyeth, are particularly well represented. You'll also find a few works by European masters, including Degas, Picasso and Renoir. The collections are spread across three separate buildings. The majority of works are found in the postmodern Charles Shipman Payson building, designed by the firm of famed architect IM Pei. The 1911 beaux-arts-style LDM Sweat Memorial Gallery and the 1801 Federal-style McLellan House hold the 19th-century American art collection.
