Kilmainham Gaol (Irish: Príosún Chill Mhaighneann) is a former prison in Kilmainham, Dublin, Ireland. It is now a museum run by the Office of Public Works, an agency of the Government of Ireland. Many Irish revolutionaries, including the leaders of the 1916 Easter Rising, were imprisoned and executed in the prison by the British, and in 1923 by the Irish Free State.
