The American Mural Project (AMP) celebrates “the art of work” through exhibits, events, and educational programs. Its centerpiece is the largest indoor collaborative artwork in the world. This five-story, 120-foot-long mural pays tribute to the ingenuity and dedication of diverse American workers on a grand scale. Launched in 2001 by artist Ellen Griesedieck, AMP seeks to inspire, educate, invite collaboration, and reveal to people of all ages the many contributions they can make to American culture as workers. More than 15,000 children and adults have collaborated on pieces of the mural. Exhibit hours are Fridays and Saturdays, 10 am–5 pm, and Sundays, 12–5 pm and by appointment.
