Portland's prison opened in 1848 for the holding of adult convicts. The purpose of a prison at Portland was largely to make use of convict labour in the construction of the breakwaters of
Portland Harbour and its various defences. The first convicts, totalling 64, arrived aboard the HM Steamer
Driver on 21 November. The Admiralty Quarries were developed for convicts to work in and once established, convict labour was providing 10,000 tons of stone per week for use on the breakwaters. The conditions within both the prison and its quarries throughout the 19th-century would later help calls for penal reform in the UK, as many prisoners died while quarrying stone. From the moment of the prison's inception, the convicts became a tourist attraction. The village of the Grove had been developed directly due to the prison, and a number of homeowners decided to open cafes from the upstairs of their houses for tourists to watch the convicts at work. In 1869 the government announced that the prison, which was originally intended to be temporary, would become a permanent establishment. Although local residents petitioned against this, it did not deter the government's plans. Between 1870 and 1872, convicts constructed the now-redundant, Grade II* Listed
St. Peter's Church just outside the prison. In 1921 the prison was converted into a
Borstal. Between 1931 and 1935, the Borstal Boys transformed a disused convict quarry into a sports stadium at the back of St. Peter's Church. The first sports day took place on 1 August 1936, while the last event spectated by the public was the Foundation Day Sports event of 1975. During World War II, an air raid on 15 August 1940 saw the Borstal's Rodney House block bombed. This left four boys dead and others severely injured, including five being admitted to hospital. In 1983, the Borstal changed to Youth Custody Centre. In 1988 the prison was re-rolled as a Young Offenders Institution (YOI, Portland), holding up to 519 young males aged 18 to 21. Accommodation at the prison was divided into seven blocks, Benbow, Raleigh, Drake, Nelson, Grenville, Collingwood and Beaufort. In 2009, the prison was the setting for
Ian Wright's Football Behind Bars, a Sky1 reality TV series showcasing Wright's work to transform the lives of 24 serious young offenders. It was based on socialising the young men by organising them in a football academy. In April 2011 the prison became an Adult/Young Offenders establishment. In late 2013, it was announced that it would also be one of a number of resettlement prisons across the UK. This news coincided with the recent decision to turn
HM Prison The Verne, another prison on Portland, into an immigration removal centre. In 2010, with the assistance of the prison, a community project was completed to restore the
Governor's Community Garden and open it to the public. Around 2011, at the Verne, the Jailhouse Cafe was opened to the public, which was created to reduce re-offending and to offer prisoners work experience. When the Verne was converted to an Immigration Removal Centre in early 2014, the cafe has continued by using prisoners from the YOI. ==YOI Inspection reports==
