Kilmainham Gaol (jail) opened in 1796 and was operational until 1924, and those years saw major rebellions in Ireland. Many of the leaders were detained and executed in the gaol, but many ordinary citizens, including children, were incarcerated as well. There’s a haunting amount of history within these stone walls, so a tour of Kilmainham Gaol is a poignant and evocative experience that offers fascinating, albeit harrowing, insight into prison life.
