Insane Asylum from WikiPedia:

A psychiatric hospital, sometimes known as an asylum, is a hospital specializing in the treatment of serious mental illness, usually for relatively long-term inpatients.

Psychiatric institutions vary widely in their goals and methods. Some hospitals may specialize only in short-term or outpatient therapy for low-risk patients. Others may specialize in the temporary or permanent care of residents who as a result of a psychological disorder, require routine assistance, treatment or a specialized and controlled environment. Patients are often admitted on a voluntary basis, but involuntary commitment is practiced when an individual may pose a significant danger to themselves or others.

Court Judges pressured the UK Government, resulting in an Act of Parliament - The Madhouse Act 1828, allowing the building of purpose-built asylums, the first of which the 1st Middlesex County Asylum was at Hanwell in West London and opened its doors in late 1831.
