Celebrate Suffolk County’s Role in America’s 250th Anniversary!

Join us in commemorating the 250th anniversary of the signing of the Declaration of Independence with a year-long series of events across Suffolk County! As one of the most historic regions in New York, Suffolk County played a pivotal role in the American Revolution. From colonial-era homesteads to battlefield sites, our rich history comes to life through reenactments, lectures, tours, festivals, and family-friendly activities.

Long before the Revolution, this land was home to the Indigenous peoples of the region, including Shinnecock, Montaukett, and Unkechaug Nations, who played a vital role in shaping the history of Long Island. We have many opportunities to delve into the intriguing ways that European settlers and Indigenous peoples contributed to our unique story in profound ways.
