Gramercy 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.
