From the late 1870s to the 1920s, the Vanderbilt family employed some of the United States's best Beaux-Arts architects and decorators to build an unequalled string of townhouses in New York City and East Coast palaces in the United States. Many of the Vanderbilt houses are now National Historic Landmarks. Some photographs of Vanderbilt's residences in New York are included in the Photographic series of American Architecture by Albert Levy (1870s).
