Preservation Long Island is a not-for-profit organization committed to working with Long Islanders to protect, preserve, and celebrate our cultural heritage through advocacy, education, and the stewardship of historic sites and collections. We were 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. Today, Preservation Long Island advances the importance of historic preservation in the region through advocacy, education, and stewardship. Working to raise awareness, appreciation, and support for the protection of a shared past, our program areas include: interpreting historic sites; collecting art and material culture pertaining to Long Island history; creating publications and exhibits; and providing direct support and technical assistance to individuals and groups engaged in local preservation efforts.

Our mission is to work with Long Islanders to protect, preserve and celebrate our cultural heritage through advocacy, education, and the stewardship of historic sites and collections.
