This map shows the operational prisons of England and Wales, colour-coded by their security category. Use the tick-boxes below the map to show or hide a category, or click any marker for the establishment’s name and location.
Locations are shown at town/site level, not exact addresses, and categories reflect each establishment’s primary current function as of September 2026 – some prisons hold more than one category of prisoner, and categorisation can change. For exact directions, visiting information or the current status of any prison, use the official GOV.UK Prison Finder.
