Dia Art Foundation was founded in 1974. A nonprofit institution, Dia plays a vital role among visual-arts organizations nationally and internationally by initiating, supporting, presenting, and preserving art projects, and by serving as a locus for interdisciplinary art and criticism. Dia presents its permanent collection at Dia:Beacon, Riggio Galleries, in Beacon, New York; exhibitions and public programming at Dia:Chelsea, in New York City; and long-term, site-specific projects in the western United States, in New York City, and on Long Island.
