20. Hyde Park
Hyde Park is the Vanderbilt estate and is one of the oldest Hudson Valley estates. Much of its 200-plus acres and historic buildings are open to the public as the Vanderbilt Mansion National Historic Site. The centerpiece of the site is fifty-four room mansion designed by McKim, Mead & White.
The mansion was constructed between between 1896–1899 and designed in the Beaux Arts style. The house was designed with all of the modern amenities only a Vanderbilt could afford at that time, including plumbing, forced hot air, central heating, and electric lighting. It was Franklin Delano Roosevelt who convinced the Vanderbilts to donate the property to the National Park Service, enabling visitors today to marvel in its grandeur.
