Coldbath Fields Prison

Coldbath Fields Prison, also formerly known as the Middlesex House of Correction and Clerkenwell Gaol and informally known as the Steel, was a prison in the Mount Pleasant area of Clerkenwell, London. Founded during the reign of James I , the prison was completely rebuilt in 1794 and extended in 1850. It was used to house prisoners on short sentences of up to two years. There were separate blocks for felons, misdemeanants and vagrants.
Coldbath Fields Prison was originally a prison run by local magistrates and where most prisoners served short sentences. Coldbath Fields also served as a debtor's prison. It took its name from Cold Bath Spring, a medicinal spring discovered in 1697. The prison housed men, women and children until 1850, when the women and children moved to Tothill Fields Bridewell in Victoria and Coldbath was restricted to adult male offenders over the age of 17. Despite its aspirations to be a more humanitarian prison , it became notorious for its strict regime of silence and its use of the treadmill.
