Raynham Hall is one of the many historic homes in the Oyster Bay area and dates back to the 1730s. Built as a "two by two," meaning two rooms of the first floor with two rooms above it. Over many years, holding its own during the American Revolution of the 1770s, the Townsend family made additions to the home until it became the Victorian-style homestead visitors see today. Raynham Hall holds 200 years of history with in its walls and is open to the public year-round for visits, tours, educational programs and research. Accredited by the American Association of Museums in 1991, it is the only house museum on Long Island to receiving such a high honor.
