Raynham Hall is a twenty-room house museum that transports you back into the life and times of the Townsends, one of the founding families of the Town of Oyster Bay on Long Island, New York.

Unfolding history from the American Revolution in the 1770s through Oyster Bay's affluent Victorian period in the 1870s, Raynham Hall was accredited by the American Association of Museums in 1991. It is the only house museum on Long Island to earn this high honor.

Raynham Hall Museum was recently honored by the State of New York as a Revolutionary War Heritage Trail site. This designation recognizes the unique contribution of the Townsend family to the cause of American independence.

The Museum is open to the public year-round for visits, tours, educational programs and research. Come see for yourself how Long Islanders from centuries past lived, learned, worked and played. Experience first-hand more than 200 years of American history, including such historic items as George Washington's August 1777 letter to New York Governor Clinton.
