Cornelius Vanderbilt Mansion, 1920.

The original Vanderbilt mansion on this location was undertaken in 1878 by Cornelius Vanderbilt II upon inheriting over $70 million from his father. The "modest" townhouse was quickly overtaken in the neighborhood by the larger, more opulent homes of other wealthy society families: Rockefeller, Carnegie, Frick, and Astor. In the spirit of competition with the other, in 1883 Vanderbilt hired George B. Post and Richard Morris Hunt to drastically expand the home. He purchased the five brownstones to the north on Fifth Avenue and had them demolished for this purpose.

The resulting mansion was the largest private residence ever built in the city (long gone, it still retains that title). It was modeled on the Château de Blois in the Loire Valley and featured skylights by John La Farge and sculptures by Saint-Gaudens in its 130 rooms. The mansion was completed in 1893.

Vanderbilt only lived in the home six years before he died of a cerebral hemorrhage in 1899. His widow and a cadre of servants continued to live in the home until she was forced to sell in 1926. Prior to its demolition, Alice Vanderbilt briefly opened the home to public and attempted to save a few of its decorative features. Today details of the house can be seen in a pair of monumental gates in Central Park, sculptural reliefs at the Sherry-Netherland Hotel, and a giant fireplace in the American Wing of the Metropolitan Museum of Art.
