HMP Portland is a category C adult and YOI in The Grove, on the Isle if Portland, Dorset. Opened in 1848, the prison has capacity to hold 580 young adult male inmates.
HMP Portland consists of four house blocks: Benbow, Raleigh, Nelson, and Grenville. Drake is the adult wing. Collingwood is the induction unit. Beaufort is the skills development unit. There is also a care and control unit.
Prisoners taking part in the “back to work” programme were given sensitive paperwork in a plan to make flammable briquettes for the prison furnace. The school, who gave the paperwork to be destroyed, said the paperwork, containing pupils’ information , was not “destroyed in the manner we expected.”
In late 2013, it was announced that a museum would be opened to cover the history of HMP Portland. The Grove Prison Museum opened in March 2014. In May 2015, it was announced that the museum had over 1,000 visitors.
