Callan Park Hospital for the Insane

The Callan Park Hospital for the Insane (1878–1914) is a heritage-listed former insane asylum, which was subsequently, for a time, used as a college campus, located in the grounds of Callan Park, an area on the shores of Iron Cove in Lilyfield, a suburb of Sydney, New South Wales, Australia. In 1915, the facility was renamed as the Callan Park Mental Hospital and, again in 1976, to Callan Park Hospital. Since 1994, the facility has been formally known as Rozelle Hospital. In April 2008, all Rozelle Hospital services and patients were transferred to Concord Hospital. The Callan Park (Special Provisions) Act, 2002 (NSW) restricts future uses of the site to health, tertiary education and community uses.

In 2015, the Government of New South Wales approved the master plan for the 61-hectare (150-acre) site and retains ownership in consultation with the Municipality of Leichhardt pending the establishment of a trust to manage the site's ongoing use as a wellness sanctuary, encompassing health, community and educational uses. Current tenants include Writing NSW (formerly the New South Wales Writers' Centre).

The current structure incorporates sandstone institutional buildings and houses that were based on designs by the colonial architects, James Barnet and Mortimer Lewis and grounds designed by botanist, Charles Moore, the founder of the Royal Botanic Gardens. The site was listed on the New South Wales Heritage Register on 2 April 1999.
