Staatsburgh State Historic Site
Coordinates: The Staatsburgh State Historic Site preserves a Beaux-Arts mansion designed by McKim, Mead, and White and the home's surrounding landscape in the hamlet of Staatsburg, Dutchess County, New York, USA. The mansion is considered a fine example of the great estates built during the Gilded Age.
In 1792, Morgan Lewis, a Governor of New York, purchased an estate covering about 334 acres (135 ha) and commissioned the construction of a colonial-style house on the site of the present day mansion. In 1832, this first house was destroyed by a fire said to be an act of arson committed by disgruntled tenant farmers. After the fire, Morgan Lewis and his wife, Gertrude Livingston, a sister of Chancellor Robert R. Livingston, immediately replaced the structure with a Greek Revival mansion with 25 rooms. The house was inherited in 1844 by Gov. Morgan Lewis's daughter Margaret and her husband Maturin Livingston; and in 1847 by the couple's son Maturin Livingston (1816–1888).
In 1890, Ruth Livingston Mills, the great-grand daughter of Morgan Lewis and the mother of Ogden L. Mills, Secretary of the Treasury, inherited the estate. Not long afterwards, Ruth Livingston Mills and her husband, the financier and philanthropist Ogden Mills, commissioned a remodelling and enlargement of the mansion to the architectural firm of McKim, Mead, and White. The principal architect was Stanford White. Work started in 1895 and when completed in the following year, had turned the house into a Beaux-Arts mansion with 65 rooms, 14 bathrooms, and 23 fireplaces. The cost of the work is reported to have cost about $350,000. As part of the process, a coal-powered electricity plant was constructed near the Hudson river to supply the electric lights in the mansion, which was also equipped with central heating. The mansion was used as a residence and for entertaining by the family, which owned five homes in total, mainly during the fall season between mid-September and the Christmas holidays. During this time, they hosted house parties, balls, and dinners. At the remainder of the year, the family stayed in one of their other residences in New York City, Paris, Newport, and California. Before her death, Ruth Livingston Mills began acquiring lands surrounding the estate. After her death in 1920, Mr. Mills continued to purchase surrounding property, enlarging the acreage of the property to total over 1,600 acres (650 ha), the size of the mansion grounds at the time that it was given to the State of New York.
In 1938, Gladys Mills Phipps donated the house and 192 acres (78 ha) of land to the State of New York as a memorial to her parents. As a State Historic Site, the estate is operated by the New York State Office of Parks, Recreation and Historic Preservation. In 1988, the Friends of Mills Mansion were organized to support the preservation and educational work at the site.
The outside of the mansion features a massive portico, balustrades, pilasters, and floral swags. The central part of the mansion is layered into a basement, 3 floors, and an attic. In the north and south wings, there is a subbasement, a basement, and two floors. Ceilings in the older part of the building dating prior to the enlargement (the first floor of the central part) are about 14 feet (4.3 m) high, whereas the ceilings of the later construction (first floor of the north and south wings) can be about 18 feet (5.5 m) high. The interior of the building is decorated in French styles of the 17th and 18th century. However, some architectural elements of the previous home have been preserved in the process.
The Mills Mansion poses several challenges to preservation: On the outside, a gray sprayed concrete finish which was added later as a preservation measure needs to be removed and replaced with a more suitable surface treatment. At the same time, the decorative cornice and many decorative elements need to be either restored or replaced. On the inside of the building, wall paint and furnishing fabrics are in need of replacement, marble and wooden surfaces need to be cleaned and the objects of the mansion's collection need to be conserved.
