The William Floyd Estate is one of the most historically significant sites on Long Island, offering visitors a rare opportunity to explore the preserved home and grounds of William Floyd, a signer of the Declaration of Independence. Located in Mastic Beach along the scenic South Shore of Suffolk County, the estate spans generations of American history, from the colonial era through the 20th century. Today, the property is maintained as part of the Fire Island National Seashore system and serves as both a museum and historic landmark.

History of the Estate

William Floyd was one of New York’s representatives to the Continental Congress and signed the Declaration of Independence in 1776. His family estate in what is now Mastic Beach became deeply tied to the story of the American Revolution and the founding of the United States.

The Floyd family occupied the property for more than two centuries. Over time, the estate evolved from a colonial farmstead into a larger country estate while still preserving many of its original structures and historical elements. The main house contains furnishings, artifacts, and architecture representing multiple periods of American history, allowing visitors to experience how generations of the Floyd family lived and worked on the property.

In 1976, the estate was added to the National Park Service as part of Fire Island National Seashore, helping preserve the property for future generations.
