After nearly 50 years in its Marcel-Breur-designed building on Madison Avenue at 75th Street, the Whitney Museum decamped in 2015 to a brand new home in Lower Manhattan's Meatpacking District, conceived by international starchitect Renzo Piano. Planted at the foot of the Highline along Ganesvoort Street, the new Whitney building boasts some 63, 000 square feet of both indoor and outdoor exhibition space. Founded in 1931 by sculptor and art patron Gertrude Vanderbilt, the Whitney is dedicated to presenting the work of American artists. Its collection holds about 15,000 pieces by nearly 2,000 artists, including Alexander Calder, Willem de Kooning, Edward Hopper (the museum holds his entire estate), Jasper Johns, Louise Nevelson, Georgia O’Keeffe and Claes Oldenburg. Still, the museum’s reputation rests mainly on its temporary shows, particularly the exhibition everyone loves to hate, the Whitney Biennial. Held in even-numbered years, the Biennial remains the most prestigious (and controversial) assessment of contemporary art in America.
