HM Prison Pentonville is an English Category B men's prison, operated by His 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. In 2015 the justice secretary, Michael Gove, described Pentonville as "the most dramatic example of failure" within the prisons estate.
