Whitney Museum of American Art, ca. 1974. Designed in the Brutalist style by Marcel Breuer in 1966, the building was the third location for the Whitney Museum of American Art. (The first two locations were on West Eighth Street and West 54th Street, respectively.) The modernist building with gray granite and reverse ziggurat facade was (and still is) a stark contrast to the surrounding 19th century brownstones, brick row houses, and postwar apartment buildings. The facade is made of 1,500 granite slabs with each weighing between 500 and 600 pounds). Ada Louise Huxtable, the New York Times architecture critic, said of the design, “the taste for its disconcertingly top-heavy, inverted pyramidal mass grows on one slowly, like a taste for olives or warm beer.” The museum always struggled with not enough space and finally in 2015 moved into a new building in the Meat Packing District. In 2016 the Metropolitan Museum of Art moved into the uptown building to display exhibitions that focus on modern and contemporary art.

The Whitney Museum is now one of New York City's unparalleled art institutions. But it took a while to get there. Here's a brief history of the Whitney Museum

When one speaks about the historic buildings of New York City, images of the stately brick rowhouses of Brooklyn, the cast-iron office buildings of SoHo, and the elaborate mansions of 5th Avenue come to mind. But the interesting architecture of the city is not limited to buildings constructed before 1900 in a classical style. Buildings built in the modern styles in the middle of the 20th century dot the streetscape and range from tall office buildings, to transportation structures, to private residences. These Mid-Century Modern buildings with their unique shapes, unusual massing, and uncommon materials (at least uncommon compared to architecture that came before) stand out from the earlier masonry buildings and the contemporary glassy structures that surround them.
