Preservation Long Island celebrates the 250th anniversary of the signing of the Declaration of Independence
Join us in commemorating the 250th anniversary of the signing of the Declaration of Independence with special events, programs, and tours across our four historic properties on Long Island. As one of the most historic regions in New York, Long Island played a pivotal role in the American Revolution.
Preservation Long Island’s historic houses, exhibition gallery, collections, and archival manuscripts reveal how local people on Long Island contributed to the unique story of our nation’s founding in profound ways. From Colonel Josiah Smith’s orderly book recording the movements of Long Island’s Minute Men in August 1776, as British forces prepared to land, to the writings of Jupiter Hammon (1711–before 1806) — America’s first published Black poet, enslaved on Long Island — whose works grappled with the moral conflicts of slavery and freedom in the early United States, Long Island’s complex and compelling history comes vividly to life.
Be sure to check this page often for additional events and announcements about special programs we are offering for America’s 250th Anniversary. We look forward to celebrating with you as we honor Long Island’s role in our shared history.
