Founded in 2001 by artist Ellen Griesedieck, the American Mural Project (AMP) is a nonprofit organization focused on honoring work in America. AMP is home to the largest indoor collaborative artwork in the world—a three-dimensional mural 120-feet long and five stories high. The mural pays tribute to American workers and highlights the varying types of work that have shaped the country over the last century. Its mission is to inspire, to educate, to invite collaboration, and to reveal to people of all ages the many contributions they can make to American culture.

More than 15,000 children and adults have helped create pieces of the mural, which is housed in one of two former mill buildings on the AMP campus on Whiting Street in Winsted, Connecticut. Programming is currently offered for schools and teachers, after-school partnerships, summer enrichment sessions, and an apprentice-style internship program. AMP's exhibit hours are Friday and Saturday, 10am–5pm, and Sunday, 12–5pm, year-round. Purchase tickets at americanmuralproject.org or in person.
