The Dia Art Foundation is a cultural organization founded in New York City in 1974 by Philippa de Menil, Heiner Friedrich and Helen Winkler. Its mission is to support, realize and preserve artistic visions.
Dia operates multiple locations in the US and Germany and sponsors projects that are often site-specific and permanent. Exhibited artists include Fred Sandback, Robert Ryman, Richard Serra, Sol LeWitt, Donald Judd and more.
In 2003, Dia opened the Dia:Beacon Museum in a former Nabisco print shop in Beacon, New York, which serves as the main exhibition space for the collection.
