Discover the William Floyd Estate

The William Floyd Estate is a center of local and national history, spanning 250 years of both change and continuity. The Floyd family name became synonymous with the American Revolutionary war effort. An active supporter of the American Revolution, William Floyd was one of four New Yorkers to sign the Declaration of Independence. He devoted himself to public service in addition to managing the Floyd family business. The Floyd family grew their enterprise as affluent merchants and landowners in the town of Brookhaven, New York, as early as the 17th century.  By 1718, the Floyds had acquired 4,400 acres on which Nicoll Floyd built the family’s ancestral home, the Old Mastic House, and ran a prosperous Northern plantation which was passed down to William Floyd and later generations. Over the years, the Estate became a summer home and was eventually donated to the National Park Service in 1975.   

The Estate’s long family history is not the only component that makes this place notable. Enslaved, indentured, and indigenous people all contributed to the Floyd family’s successes. Their skill and labor played an integral role in the operation of the Floyd plantation and other lucrative industries such as whaling, which defined the family’s history in Mastic Beach. The experiences of the enslaved, indentured, and indigenous left their impact on this historical landscape. While their presence at the Estate seems contradictory to William Floyd’s participation in the fight for American independence, we can shed light on our nation’s controversial past by telling well rounded stories that allow us, as a people, to reconcile with the past to create a more equitable future.

The site is ideal for birding, especially during spring and fall migration, attracting a variety of bird species such as warblers and providing habitat for common backyard birds, hawks, and owls year round. The Estate is dog friendly, but dogs must be on a leash 6 feet or shorter.
