A magnet for history buffs and bird watchers, Green-Wood is a Revolutionary War historic site (the Battle of Long Island was fought in 1776 across what is now its grounds), a designated site on the Civil War Discovery Trail and a registered member of the Audubon Cooperative Sanctuary System.

The Green-Wood Historic Fund publicizes and interprets the architecture, specimen trees, gardens, glacial ponds, cast-iron signage and fences, tombs, mausoleums, sculptural monuments and animal habitats on the cemetery’s 478 acres. The organization also maintains and restores monuments and buildings that it deems of historical, cultural or architectural importance.
