Knox's Headquarters State Historic Site, in the town of New Windsor in Orange County, New York, consists of the Georgian house of the Ellison family, built in 1754 by immigrant William Bull[3][4] of Hamptonburgh, NY, and the grounds around it. The site is located on Old Forge Hill Road, just south of Route 94 east of Vails Gate.
Today, the house can be toured when the site is open. It is used to educate visitors about how 18th-century families such as the Ellisons actually lived. On holidays and special occasions staff dress in reproduction period clothing and give special events. Staff dressed as the 2nd Continental Artillery frequently demonstrate cannon use on the grounds during special events, as Knox was best known for his command of Continental artillery.
The house and its grounds were the setting and subject of the children's haunted-house novel Buried Treasure: A Tale of an Old House (1919), by the best-selling children's author Henry Everett McNeil. The book is illustrated with McNeil's own photographs (made circa 1911 or 1912) of the various buildings and bridge at the Knox site.
The Jane Colden Plant Sanctuary along some of the trails in the nearby woods memorializes America's first female botanist, who also resided in the area.
