HM Prison Wealstun is a Category C men's prison, located near the village of Thorp Arch in West Yorkshire, England. The prison is operated by Her Majesty's Prison Service.HistoryWealstun Prison was formed from the almagamation of HMP Thorp Arch and HMP Rudgate on 1 April 1995; both built in 1965, on the site of ROF Thorp Arch). The amalgamation of two neighbouring establishments was an historic development for the Prison Service, and had the effect of creating a category C closed side and category D open side within one establishment. A great deal of building development has taken place at the prison in recent years, and has recently been completed..In June 2003, 20 prisoners were involved in a rooftop protest at Wealstun Prison. The inmates smashed windows and climbed up drainpipes and ledges to the roof of the jail. After 19 hours some of the prisoners came down from the roof, but some of the inmates lasted 30 hours on the roof before surrendering peacefully.In February 2004, an inspection report from Her Majesty's Chief Inspector of Prisons criticised Wealstun Prison for being mouldy, damp and infested with rats. The report made 135 recommendations for improvements at the jail, and stated that in parts of the prison there was no alarm system, basic repairs had been neglected and windows were smashed or missing. However following a more recent inspection, HMP Wealstun was highly praised for the work undertaken there.
