The Metropolitan Asylums Board purchased the site where St Ann's Hospital now stands in August 1892.[1][2] The hospital, which was initially known as the North Eastern Fever Hospital and treated patients suffering from fever and diphtheria, opened in October 1892.[2] Building work on the administration block began in 1898 and construction of the laundry began the following year.[2]
The Metropolitan Asylum Board was liquidated in 1929 and the hospital came under the administration of London County Council in 1930.[3] The hospital joined the National Health Service in 1948 under the management of the Tottenham Hospital Management Committee, part of the North East Metropolitan Regional Hospital Board.[2] The hospital was renamed St Ann's General Hospital in 1951.[2] It came under the responsibility of Haringey Health Authority in 1982 and transferred to the management of Barnet, Enfield and Haringey Mental Health NHS Trust in 2001.[2]
