The Castellani Museum has a permanent collection of 5700 works of art, including prints, photographs, paintings, drawings, and sculpture dating largely from the 1850's to the present.
19th-century & 20th century Europeans include Daumier, the impressionist Guillaumin, Utrillo, Rouault, Modigliani, Picasso, Miro, Moholy-Nagy, and Dali; and American artists like Twatchman, Bierstadt, Cropsey, and Potthast, Avery, Burchfield, and Tomlin.
While the collection illustrates the development of modern art, it focuses primarily on art from the 1970's to the present. Modern and contemporary artists represented include Calder, Nevelson, Warhol, Motherwell, DeKooning, Bearden, Hepworth, Nevelson, Rauschenberg, Basquiat, Haring, and Baselitz.
Exhibitions of nationally known and emerging contemporary artists and traditional folk arts are presented each year.
