The Hudson Valley's grand estates were built by people who shaped American history: a U.S. president, a telegraph inventor, a Supreme Court justice, an artist who designed his own house. Their homes still stand—some preserved exactly as they left them, others opened as museums with the families' original furnishings and libraries intact. You'll find Federal-era mansions and Gothic Revival palaces, quarry ponds reshaped by hand, underground galleries carved to hold masterpiece art collections. Most cluster near the river between Garrison and Tarrytown, with others scattered through Kingston, Poughkeepsie, and Hudson. Many offer guided tours; several sit on working estates or grounds you can walk. This list holds the houses that changed American design and the lives lived inside them.
A Gothic Revival mansion built for one Gilded Age fortune and furnished by another: Jay Gould filled it with Tiffany windows and, after his first greenhouse burned in 1880, a supposedly fireproof Lord & Burnham replacement that held 6,000 orchids. The iron greenhouse frame still stands, stripped bare, next to a rose garden that peaks in June.
