The district contains 26 contributing buildings, two contributing sites, and one contributing structure. They are associated with three
estates:
Beechwood, Rosemont, and
Woodlea (now Sleepy Hollow Country Club);
The Clear View School, a school complex; two religious properties: Saint Mary's Episcopal Church and Scarborough Presbyterian Church; and Sparta Cemetery, which dates back to before the Revolutionary War. All properties stand in much the same condition as when first nominated, except Rosemont, which was demolished in the mid- to late-1980s. Several properties within the district exemplify Mid-19th Century
Revival architectures, including Greek, Gothic, Renaissance, and Neoclassical styles; their formal landscaping exemplifies estate landscaping at the turn of the 19th century. Most of the properties were established by wealthy landowners, ranging from the late 18th century to the early 20th century. The district, which remains generally rural and sparsely developed, borders the
Hudson River and lies within the towns of
Ossining and
Mount Pleasant, between the villages of
Ossining and
Sleepy Hollow. Most of the district's buildings are set on large parcels of land, and many are clearly visible from
U.S. Route 9 (the former
Albany Post Road), the district's major thoroughfare. Stone and brick walls line Route 9 within the boundaries of the district. The district achieved State Register status on August 6, 1984, National Register district status on September 7, 1984, and local landmark status on January 5, 1988. ==Beechwood==
