Parkhurst Prison is one of three prisons on the Isle of Wight.  It was once among the few top-security prisons in the UK, but was downgraded in the 1990s following a major escape.  Two murderers and a blackmailer broke out of the prison on 3 January 1995 and enjoyed four days of freedom before being recaptured.  

Parkhurst was notorious as one of Britain’s toughest jails.  Inmates have included the Yorkshire Ripper Peter Sutcliffe, Moors Murderer Ian Brady, and gangsters the Kray twins.

It was built as a military hospital in 1805, and later converted into a prison for boys awaiting deportation, mainly to Australia, in 1835.
