An official Path Through History Site! The 23-acre Jay property, overlooking Long Island Sound in Rye, was the boyhood home of New York State’s only native founding father, John Jay (1745-1829), who later served as America's first chief justice of the Supreme Court and author of the Jay Treaty. Jay was also an important advocate for emancipation and served as president of the Manumission Society in New York. It is part of the Boston Post Road Historic District, a National Historic Landmark and a stop on Westchester County’s African American Heritage Trail. The Greek Revival mansion, the centerpiece of the property, was built by Peter Augustus Jay in 1838 and is being restored and managed by the nonprofit Jay Heritage Center. It is open Sundays, 2-5 p.m. (April - November) and by appointment for docent-led and self-guided tours. A second restored building, the 1907 Van Norden Carriage House, is Jay Heritage Center's visitor and education center and exhibit gallery. It is open Wednesday - Friday, 10 a.m.-4 p.m. (April - November) and for programs all year. The Jay property, originally acquired by Westchester County in 1992, is an environmentally significant area at the headlands of the watershed of an adjacent county park, Marshlands Conservancy. The Jay property has been owned in conjunction with New York State since 1997 and is managed by Westchester County Parks as dedicated state and county parkland. It is used for recreation, historic education and conservation purposes.
