Est. 1903 · Operated as Orphan Asylum of Brooklyn 1942–1965, housing 500+ children · Home of Islip Art Museum, established 1985 · Brookwood Hall Park — public waterfront grounds on Great South Bay
H.K. Knapp built Brookwood Hall in 1903 on the south shore of Long Island, replacing an earlier resort called Stellenwerf's Lake House Hotel on the same site. The property fronts Champlin Creek and the Great South Bay, giving the mansion grounds a distinctly waterfront character that later proved consequential to its haunting reputation.
The Thorne family purchased the estate in 1929 and occupied it through the Depression years. In 1941, as private estates became financially untenable, the property transitioned to the Orphan Asylum of Brooklyn. From 1942 to 1965 the institution housed more than 500 children — an enormous number for a single residential property on the South Shore. The orphanage closed in 1965 as foster care placement became the dominant model for child welfare in New York State.
The Town of Islip subsequently took ownership and repurposed the building for municipal offices. In the early 1970s, the Islip Art Gallery was founded by art patron Elizabeth Vaughan, initially operating from a gatehouse at the entrance. After that gatehouse burned, the gallery relocated to the mansion's south wing. It was formally incorporated as the Islip Art Museum in 1985 through a partnership with the Town of Islip. The New York Times once described it as the best facility of its kind outside Manhattan.
The mansion received extensive renovations in recent decades to restore its original appearance. The Islip Art Museum has been closed since April 2020 pending operational decisions; the grounds and exterior remain accessible as part of Brookwood Hall Park.

Child crying heard inside former orphanage roomsUnexplained cold spotsYoung boy apparition at water's edge who vanishes
The haunting accounts at Brookwood Hall cluster around two recurring phenomena, both centered on children. Staff working in the former orphanage sections of the mansion have reported hearing a child crying — audible enough to prompt searches — and encountering unexplained cold spots in rooms where no draft source exists.
The more striking accounts come from outside. Multiple visitors walking the grounds along Champlin Creek have reported the same image: a young boy sitting at the water's edge, staring out across the creek, who vanishes when the observer looks away or approaches. The descriptions are consistent across unconnected accounts — a seated child, motionless, facing the water — with no explanation for his disappearance.
The Long Island Paranormal Investigators, who have documented paranormal claims at multiple Long Island sites, list Brookwood Hall among Suffolk County locations with staff-reported activity. The site's history — more than 500 children housed in institutional conditions over 23 years, in a building that still looks much as it did during the orphanage years — gives the accounts a structural plausibility that's unusual for waterfront ghost-tourism sites.
