The facility, which is located just south of a ruined
Augustinian priory, opened as a
mental health facility in 1949. A "special care colony" for people with an
intellectual disability, with capacity of up to 1,000 patients, was added in 1958. The staff failed to realise in 2017 that the hospital's new CCTV system was recording all activities in the hospital. Some 300,000 hours of footage was discovered including "accounts of patients facing appalling cruelty and physical abuse, and being ignored while seriously unwell." This case has been called "the largest systemic abuse case uncovered in the UK". ==Statutory inquiry==
