Welcome to the Vanderbilt Mansion

The Mansion.

On behalf of the National Park Service, welcome to Vanderbilt Mansion National Historic Site. Before you stands the only Gilded Age mansion in the National Park Service, “Hyde Park.” This was the country place of Frederick and Louise Vanderbilt, used primarily in the spring and fall. Built over 26 months between 1896 to 1898, at the cost of $660,000, it is one of the best-preserved examples of a Gilded Age home in the US. The approx. 45,000 square-foot building consists of 54 rooms and six floors. It is designed in the Beaux-arts, neo-classical style and was constructed using innovative techniques, particularly applied skyscraper technology. It is supported by steel beams and cement, with an exterior made of Indiana limestone.
