Built by John D. Rockefeller, Kykuit is one of the finest preserved houses in the nation. This six-story classical revival stone mansion has been home to four generations of the Rockefeller family. During your tour of this historic site, you can stroll through the Beaux Arts gardens which contain an exceptional collection of 20th-century sculpture from such artists as Pablo Picasso, Henry Moore, and Alexander Calder, private, underground art galleries with Picasso tapestries, classic automobiles, and horse-drawn carriages.
