Built in 1792 on the site of a medieval castle, HM Prison Gloucester operated for over two centuries before closing in 2013—and its ghosts are said to have remained on duty. The most reported figure is “The Gaoler,” a stern Victorian officer seen patrolling the cell blocks and vanishing through iron doors. Inmates and staff long spoke of a hanged soldier who appears in the execution yard, his shadow forming even on overcast days. Paranormal teams have documented heavy footsteps, cell doors slamming, and whispered pleas near Death Row, where public executions once drew thousands. Since reopening for heritage tours, visitors frequently capture disembodied voices on EVPs and faces in the narrow observation mirrors.
