About Gramercy Park
View All Gramercy Park ListingsGramercy Park is one of New York City’s most storied and architecturally distinctive neighborhoods, centered around the only private park in Manhattan. The area exudes old-world charm with its gas-lit streets and impeccably preserved 19th-century architecture. While the park itself is private, the surrounding real estate offers a mix of historic brownstones, elegant pre-war cooperatives, and boutique new developments that cater to those seeking a low-traffic urban retreat.
