Stuyvesant Square is a tranquil park and surrounding neighborhood in the Gramercy area, centered on the four-acre green donated to the city in 1836 by Peter Gerard Stuyvesant, great-great-grandson of the Dutch colonial governor, enclosed by the oldest surviving cast-iron fence in New York City. The neighborhood roughly bounded by 14th and 19th Streets between First and Third Avenues retains a genteel residential character shaped by its proximity to Gramercy Park, with St. George's Church and Beth Israel Medical Center (now closed) among its historic landmarks.
