From 2016 to 2020, the museum operated a modern and contemporary art gallery at 945 Madison Avenue, a Marcel Breuer-designed building at Madison Avenue and 75th Street in Manhattan's Upper East Side, the former Whitney Museum of American Art. It extends the museum's modern and contemporary art program. In September 2018, it was announced that the Met intended to vacate the Met Breuer three years early, in 2020; the Frick Collection began occupying the space as its main building undergoes renovations.
