From HMP Wakefield, infamously known as Monster Mansion, to the maximum-security fortress of HMP Belmarsh, we count down the 10 most dangerous prisons in the United Kingdom and explore the darkest corners of the British prison system and its most dangerous inmates.

We go inside Durham Prison, Swansea, Wormwood Scrubs, HMP Addiewell, Pentonville, Wandsworth, Strangeways, Belmarsh, Frankland, and Wakefield while profiling serial killers, organised crime figures, and terrorists who have occupied these cells.

If you're a fan of true crime documentaries, prison stories, and UK crime history, subscribe for twice-weekly deep dives into the world's most dangerous institutions.
