Long Lartin, which occupies the site of a former war department ordnance depot, was built in the 1960s and opened as a prison in 1971. Although originally opened as a category C prison, it was upgraded to provide dispersal level security in 1973. Further improvements in security were made between 1995 and 1997, and an additional wing, Perrie, was opened in June 1999. In 2009 a new purpose built unit, Atherton, replaced older style wings, increasing the capacity of the prison.
