Dia:Beacon, Riggio Galleries is the museum for the Dia Art Foundation's collection of art from the 1960s to the present. It is one of the largest exhibition spaces in the country for modern and contemporary art. Dia pioneered the conversion of industrial buildings for the installation of contemporary art, a practice and aesthetic now widely adopted by museums and galleries internationally. Dia's most recent conversion, its museum in Beacon, is located in a former printing plant built in 1929 by Nabisco (National Biscuit Company). Along with Dia's permanent collection, Dia:Beacon also presents temporary exhibitions, as well as public programs designed to complement the collection and exhibitions.
