From MI5 headquarters to a penal dustbin: the turbulent history of Wormwood Scrubs

Countries & Cities · Published 10 October 2026 Swipe more like this →

In short: Wormwood Scrubs began as a makeshift prison built by inmates in 1874. It has since served as a wartime intelligence hub for MI5, a site of notorious escapes, and a flashpoint for systemic failure. Today, this Grade II listed facility remains one of London's most complex and controversial penal institutions.

Construction of the permanent prison began in 1874, utilizing bricks manufactured on-site by prisoners. Designed by Sir Edmund Frederick Du Cane, the facility was completed in 1891. Its history is marked by dramatic shifts in purpose; during the Second World War, the War Department requisitioned the site. MI5 moved its headquarters there in 1939, with staff famously locking themselves in their new cell-offices. The site also hosted the Radio Security Service and the Chief Cable Censorship Department, an outstation of Bletchley Park, while anti-aircraft batteries operated nearby.

The prison's reputation has fluctuated wildly. In 1979, a major riot over visiting rights led governor John McCarthy to label the facility a penal dustbin. The 1990s saw a scandal involving staff brutality, resulting in the conviction of several officers and millions of pounds in settlements. Reports from the Chief Inspector of Prisons have oscillated between praise for fundamental improvements and condemnation for filth, overcrowding, and systemic neglect. In 2018, the death of Winston Augustine in the segregation unit—caused by a lack of food and medication—highlighted severe failures in duty of care.

Today, Wormwood Scrubs operates as a Category B prison for adult males, featuring five main wings and specialized units like the Conibeere Unit for substance misuse. Despite its Grade II* listed gatehouse, the prison struggles with the realities of modern incarceration. Recent years have seen incidents ranging from the 2024 escape of a prisoner from a hospital visit to the 2026 arrest of 86 protesters. The facility remains a focal point for debates on prison reform, symbolized by the reliefs of reformers Elizabeth Fry and John Howard on its facade.
