The Boston Post Road Historic District is a historic district including 3 pre-civil war mansions and their grounds, a 10,000 year old Paleo-Indian meadow and viewshed, a cemetery, and a nature preserve. It touches on the south side of the nation's oldest road Boston Post Road (US 1) in Rye, New York where mile marker “24” out of 230, designated in 1763 by Benjamin Franklin, is set into the perimeter wall; from there the landmarked area of 286 acres expands down to the Milton Harbor of the Long Island Sound. Two of the mansions included in the landmark district are Greek Revival; the third is Gothic Revival and was designed by Alexander Jackson Davis.
This site with its archaeological significance and importance to American heritage was declared a National Historic Landmark in 1993
The 1838 Peter Augustus Jay House now being restored by the not-for-profit organization, The Jay Heritage Center, is one of two Greek Revival residences. It is situated on the Jay Property, the boyhood home of Founding Father John Jay. The existing house was built upon the footprint of an older 18th-century farmhouse, The Locusts, and replaced with the current mansion by John Jay's eldest son, Peter Augustus Jay. It seems to have been built by Edwin Bishop based on architectural pattern books by Minard Lafever and Chester Hills., p. 13. Restoration of the house is an official Save America's Treasures project. The site is also on the Westchester County African American Heritage Trail.
