The luxurious lifestyle enjoyed by two wealthy 18th-century Connecticut Valley families—until their fortunes collapsed—is displayed in the Phelps-Hatheway House and Garden. Merchant Shem Burbank built the house in 1761. As a Tory sympathizer, his business suffered during the American Revolution. In 1788 he sold the house to Oliver Phelps, who in 1794 flaunted the riches earned from land investments in western New York by adding a wing, an architectural masterpiece that still features original Paris-made wallpaper. Eight years later Phelps left Suffield, bankrupted by his failed land schemes. The house is furnished with outstanding 18th-century Connecticut furniture and landscaped with formal flower beds. The Hatheway family owned the house throughout the 1800s, accumulating an attic full of artifacts that document life during that century.

The house offers tours.

Staatsburgh is a New York State Historic Site located within the boundaries of Mills-Norrie State Park. It provides an example of the great estates built by America's financial and industrial leaders during the Gilded Age. A 25-room Greek Revival structure was built on the site in 1832 by Morgan Lewis and his wife, Gertrude Livingston, replacing an earlier house that had burned down. This second house was inherited by Ruth Livingston Mills, wife of noted financier and philanthropist Ogden Mills. In 1895, Mr. and Mrs. Mills commissioned the prestigious New York City architectural firm of McKim, Mead, and White to remodel and enlarge their Staatsburg home. After completion in 1896, the house was transformed into a Beaux-Arts mansion of 65 rooms and 14 bathrooms. Its exterior was embellished with balustrades, pilasters, floral swags, and a massive portico. The rooms were furnished with elaborately carved and gilded furniture; fine oriental rugs; silk fabrics; and a collection of art objects from Europe, ancient Greece, and the Far East.

The site offers tours and educational and recreational programs and events.
