William Floyd Estate reopens, marks nation’s 250th anniversary in Suffolk County
After years closed for renovations, the Old Mastic House reopened with colonial re-enactors and artifacts, putting Suffolk face to face with the nation’s 250th year.
The Old Mastic House at the William Floyd Estate has reopened in Mastic Beach, bringing one of Suffolk County’s most important Revolutionary-era sites back into public view just as the nation approaches its 250th anniversary. The house, long closed for renovations, officially reopened to the public on Sunday, May 2, after a celebration on Friday, May 1 that turned the estate into a living history scene.
Visitors at the reopening found more than a ribbon-cutting. Colonial re-enactors, historical literature, wares and musical instruments helped recreate the world that once filled the estate, giving families and students a close look at the era instead of a lesson confined to a textbook. The event tied the restored house to a larger moment for Suffolk County, which is beginning to mark the semiquincentennial through a site that links local heritage to the founding of the United States.

That link runs directly through William Floyd, one of only four New Yorkers to sign the Declaration of Independence. Floyd signed the document on July 6, 1776, and his family’s Long Island home became part of the Revolutionary War itself when British forces occupied the island later that year. Floyd’s wife and children fled to Connecticut, the house was used as a barracks, and Loyalists later plundered it.
The Old Mastic House itself goes back to around 1724, when it was built for Floyd’s father, Nicoll Floyd. The estate today includes the 25-room house, twelve outbuildings, the family cemetery and 613 acres of forest, fields, marsh and trails. The National Park Service says enslaved, indentured and free labor were used in constructing the house and working the land, a reminder that the story of the estate includes both patriotism and the hard realities of who built and maintained such places.

The National Park Service describes the William Floyd Estate as a center of local and national history spanning 250 years of change and continuity. The grounds are open year-round from 9 a.m. to 4 p.m., and the Old Mastic House is normally open for tours from May through September. Suffolk County has also designated Dec. 17 as William Floyd Day, giving the estate another place in the county’s public calendar as residents look toward 2026 and the nation’s 250th anniversary.
