It has been used as a young offenders prison mainly by women. The prison is unique in that "way" it also had a therapy section which offered to help the juveniles with social and behavioural disturbances (including ADHD) and was more akin to a rehab centre during day, and prisoners in their cells at night. The prison closed completely in 2006.
