HMP Haverigg has the reputation of being the prison services most isolated establishment. It opened in 1967 on the site of a former RAF camp and is the only prison in Cumbria. Originally, 350 prisoners were accommodated in the RAF billets, but the addition of new accommodation and the rebuilding of two units following incidents of concerted indiscipline in 1988 and 1999 increased accommodation to 558 places. Additional places were created through further new units and doubling of cells.
