Mission

Working with Long Islanders to protect, preserve and celebrate our cultural heritage through advocacy, education, and the stewardship of historic sites and collections. Our organization was founded in 1948 as the Society for the Preservation of Long Island Antiquities in response to intense post-World War II development with a mission to preserve individual historic buildings and artifacts through the creation of house museums. In 2017, we adopted a new name to communicate our core mission more clearly to all Long Islanders. Today, Preservation Long Island continues to support historic preservation in communities across the region while raising awareness about the significance of Long Island's dynamic history and cultural heritage.

Advocacy

Preservation Long Island has championed the preservation of historic places and neighborhoods throughout the region since 1948, encouraging community-based alternatives to demolition, overbuilding, and civically insensitive redevelopment. This work includes providing technical support and advisory services to individuals and groups engaged in local preservation efforts as well as our list of Endangered Historic Places, which seeks nominations from the public every other year. Our biennial Awards also recognize exemplary achievement in preservation across Long Island.

Population(s) Served
Adults

Preservation Long Island's educational programming shares our region's diverse cultural heritage with students. We offer several on-site programs for school groups carefully designed to reinforce Common Core and New York State Next Generation learning standards across grade levels and curriculums. Each of our distinctive historic properties allows students to contextualize classroom topics such as the American Revolution, Slavery, Emancipation, Maps & Globes, Trade, the Constitution, and more.

At Preservation Long Island's gallery, located at our headquarters in Cold Spring Harbor, we connect visitors with the stories of Long Island's remarkable past through changing exhibitions that showcase four centuries of fine and decorative arts, architecture, historic documents, and material culture from across the region.

Our collections encompass one of the most significant regional assemblages of material culture in New York State, with over 8,000 objects and archival materials ranging from artistic and technological masterworks to documentary imagery and everyday artifacts.

Charting impact

Four powerful questions that require reflection about what really matters - results.

Promote better board and public engagement, strengthen fundraising, increase visibility, and achieve institutional sustainability. The primary Collections goals include strengthening collections management, security, and accessibility by improving intellectual control over databases and objects on-site and in storage; digitizing collections for public access, research and exhibitions; and improved and improving environmental controls at
all facilities.

Successful adoption of new governance documents, brand messaging through name change, increased professional staff, and efforts to improve poor fundraising outcomes. Recent outcomes include the hiring of a development professional in 2023 whose focus has been intentional community and constituent engagement which includes receiving feedback and creating a more inclusive experience.

Collections-focused staff hires, continued conservation by priority, creation of a publicly accessible collections digital database, new collection forms and updated collection policies, an archive needs assessment and preservation survey, a historic housekeeping handbook, a risk assessment for collections and historic properties, and an emergency response plan. Currently in progress is a full baseline object collections inventory at all PLI facilities that will inform how PLI plans, prioritizes, and implements all future collections management initiatives towards improved preservation and public access, both actual and virtual.
