Castle Hill Lunatic Asylum was Australia's first official institution which provided care for the mentally ill. It was located approximately 7 miles (11 km) north of Parramatta in New South Wales. Established by Lachlan Macquarie in May 1811, it operated until 1826. It was housed in a two-storey stone building, previously a granary, which also served as a barracks at one time.
