Kykuit, known also as the John D. Rockefeller Estate, is a 40-room historic house museum in Pocantico Hills, a hamlet in the town of Mount Pleasant, New York 25 miles (40 km) north of New York City. The house was built for oil tycoon and Rockefeller family patriarch John D. Rockefeller. Conceived largely by his son, John D. Rockefeller Jr., and enriched by the art collection of the third-generation scion, Governor of New York, and Vice President of the United States, Nelson Rockefeller, it was home to four generations of the family. The house is a National Historic Landmark owned by the National Trust for Historic Preservation, and tours are given by Historic Hudson Valley.
