The Peace Tower (also known as The Artists' Tower of Protest) was a collaborative artwork spearheaded by the artists Irving Petlin and Mark di Suvero. The Peace Tower was created in the winter of 1966 in the West Hollywood neighborhood of Los Angeles to protest US involvement in the Vietnam War. Forty years later, Mark di Suvero, Irving Petlin, and Rirkrit Tiravanija collaborated in revisiting the project through a new installation entitled Peace Tower (2006) for the Whitney Museum of American Art in New York City to protest the Iraq War.
