Vanderbilt Mansion National Historic Site - http://www.nps.gov/vama

The Vanderbilt Estate in Hyde Park, New York is perhaps the best, most intact example of the types of estates constructed by wealthy industrialists in the 19th century. The fully-furnished, 54-room mansion is placed in a wondrous landscape with breathtaking views of the Hudson River and distant Catskill Mountains. It offers a glimpse into a past world known by only an elite few.
