Background
The New Prison was a prison located in the Clerkenwell area of central London between c.1617 and 1877. The New Prison was used to house prisoners committed for examination before the police magistrates, for trial at the sessions, for want of bail, and occasionally on summary conviction. It was rebuilt three times: in 1773, 1818 (after being burnt down in the Gordon Riots of 1780), and in 1847. At this time it was renamed the Clerkenwell House of Detention, also known as Clerkenwell Prison. It was the site of a notorious bomb outrage, the Clerkenwell explosion in 1867.
