Rockwood Hall was a Gilded Age mansion in Mount Pleasant, New York, on the Hudson River. It was best-known as the home of William Rockefeller, brother of John D. Rockefeller, both co-founders of the Standard Oil Company. Other owners of the house or property included Alexander Slidell MacKenzie, William Henry Aspinwall, and Lloyd Aspinwall. The property was once up to 1,000 acres (400 ha) in size; the mansion at its height had 204 rooms, making it the second-largest private house in the U.S. at the time, only behind the Biltmore mansion in North Carolina. The estate is currently an 88-acre (36 ha) section of the Rockefeller State Park Preserve. Among the first people to live on the property was Alexander Slidell Mackenzie, who lived there from 1840 to 1848. Edwin Bartlett, a wealthy merchant, subsequently purchased the site and hired Gervase Wheeler to design a house on the property, which was constructed in 1849. By 1860, Bartlett sold the house to William Henry Aspinwall, who lived there until 1875; his son Lloyd lived at the house until 1886. William Rockefeller purchased the estate and likely extensively renovated the house and property, hiring the firm Carrère and Hastings for interior renovations. Rockefeller died there in 1922, and his heirs sold it to investors, who turned the house and property into Rockwood Hall Country Club. The club became bankrupt in 1936, after which it became the Washington Irving Country Club. By 1940, the property lay empty again, so its owner John D. Rockefeller Jr. had most of the property's buildings razed, including the mansion. In late 1946, the Rockwood Hall property was proposed for the location of the United Nations headquarters. John Jr.'s son Laurance Rockefeller sold some of the property to IBM in 1970. IBM's property was later bought by New York Life, followed by Regeneron Pharmaceuticals, the current owner. The remaining property was sold to New York State at a significantly reduced price to become parkland within Rockefeller State Park.

Sleepy Hollow is a village in the town of Mount Pleasant, in Westchester County, New York, United States. The village is located on the east bank of the Hudson River, approximately 30 miles (48 km) north of New York City, and is served by the Philipse Manor stop on the Metro-North Hudson Line. To the south of Sleepy Hollow is the village of Tarrytown, and to the north and east are unincorporated parts of Mount Pleasant. The population of the village at the 2020 census was 9,986.Originally incorporated as North Tarrytown in the late 19th century, in 1996 the village officially adopted the traditional name for the area. The village is known internationally through "The Legend of Sleepy Hollow", an 1820 short story about the local area and its infamous specter, the Headless Horseman, written by Washington Irving, who lived in Tarrytown and is buried in Sleepy Hollow Cemetery. Owing to this story, as well as the village's roots in early American history and folklore, Sleepy Hollow is considered by some to be one of the "most haunted places in the world". Paradoxically, Sleepy Hollow has also been designated "the safest small 'city' [i.e., under 100,000 residents] in America".The village is home to the Philipsburg Manor House and the Old Dutch Church of Sleepy Hollow, as well as the Sleepy Hollow Cemetery, where in addition to Irving, numerous other notable people are buried.

The Pocantico River is a nine-mile-long (14 km) tributary of the Hudson River in western central Westchester County, New York, United States. It rises from Echo Lake, in the town of New Castle south of the hamlet of Millwood, and flows generally southwest past Briarcliff Manor to its outlet at Sleepy Hollow. Portions of the towns of Mount Pleasant and Ossining are within its 16-square-mile (41 km2) watershed. Writer Washington Irving, who lived in the area for most of his life, was inspired by the undeveloped area above the river's mouth to write his classic "The Legend of Sleepy Hollow". Later in the 19th century much of the land was purchased by the Rockefeller family as part of their Kykuit estate; today much of that land has become Rockefeller State Park Preserve. A former reservoir used by the city of New Rochelle has likewise been converted into county-run Pocantico Lake Park. While the river runs predominantly through those parks and suburban land, it is still one of the most polluted tributaries of the Hudson.
