A Walk Through Time

Enjoy a walk through time when you visit the William Floyd Estate. The Estate was at the center of the Floyd Family's life for more than 250 years and the ancestral home, grounds, outbuildings, and family cemetery help tell the story of the continual use, change, and adaptations that took place here in Mastic Beach, New York.

The William Floyd Estate, which was authorized as an addition to Fire Island National Seashore, is located on the mainland of Long Island. Two hundred and fifty years of history are preserved at the Estate.

From Memorial Day to Columbus Day, visitors can explore the estate grounds, including twelve outbuildings, the family cemetery, and 613 acres of forest, fields, marsh, and trails. The Old Mastic House, temporarily closed due to preservation work, contains a variety of architectural features and artifacts from three centuries of American life, the story of the family, and their use and enjoyment of this place.

William Floyd

William Floyd, a signer of the Declaration of Independence, was born in the house in 1734. In 1976 William Floyd's great-great-granddaughter, Mrs. Cornelia Floyd Nichols, and her children donated the house to the National Park Service.

Of the four New Yorkers who signed the document, his is the only house still standing and open to the public.
