The Lockport Gallery features changing exhibitions of art created by past and contemporary Illinois artists and artisans. Paintings, drawings, sculptures, quilts, and other decorative and ethnographic arts are showcased in rotating, theme-based exhibitions augmented by interpretive materials. The exhibitions are given an added dimension through educational events, group tours, and outreach activities for both children and adults.

The ISM mission is fulfilled through collecting, research, exhibits, publications, and interpretive programs that enhance educational experiences, aesthetic values, and in general, the quality of life.
