HMS Belmarsh

HM, or ‘her Majesties’ Prison Belmarsh is a ‘category A’ men’s prison located in Greenwich, South East London. Though only active as a high security prison since 1991, the facility has grown famous in the UK as well as further afield. Housing some of Britain’s most notorious and revered criminals during its two decades, Belmarsh’s current population stands around the 1,000 mark. As well gaining a reputation for housing such notorious offenders as Charles Bronson and Ronnie Biggs, Belmarsh is also noted for its previous reputation as the ‘British Guantanamo’, due to its use for the detainment of untried ‘terror charge’ prisoners in the early 2000’s following 9/11.
