HM Prison Pentonville 4.07

HM Prison Pentonville is an English Category B/C men's prison, operated by Her Majesty's Prison Service. Pentonville Prison is not in Pentonville, but is located further north, on the Caledonian Road in the Barnsbury area of the London Borough of Islington, north London.HistoryThe first modern prison in London, Millbank, opened in 1816. It had separate cells for 860 prisoners and proved satisfactory to the authorities who started building prisons to deal with the rapid increase in numbers occasioned by the ending of capital punishment for many crimes and a steady reduction in transportation.Two Acts of Parliament allowed for the building of Pentonville prison, designed by Captain Joshua Jebb, Royal Engineers, for the detention of convicts sentenced to imprisonment or awaiting transportation. Construction started on 10 April 1840 and was completed in 1842. The cost was £84,186 12s 2d.It had a central hall with five radiating wings, all visible to staff at the centre. This design, intended to keep prisoners isolated – the "separate system" first used at Eastern State Penitentiary in Philadelphia – was not, as is often thought, a panopticon. Guards had no view into individual cells from their central position. Pentonville was designed to hold 520 prisoners under the separate system, each having his own cell, 13ft long, 7ft wide and 9ft high with little windows on the outside walls and opening on to narrow landings in the galleries.
