Green-Wood Cemetery, a grand feature of the Brooklyn landscape since 1838, is one of the city’s most remarkable and expansive greenspaces. But did you know it is an accredited arboretum with a world-class Tree Walk? It is also a de facto bird sanctuary threaded by a Nature Walk, a unique education in architectural history and art appreciation, and the final resting place of celebrated New Yorkers from Louis Comfort Tiffany to Jean-Michel Basquiat.
