Kilmainham Jail is perhaps the most important building in modern Irish history. A place of incarceration since its construction in the late eighteenth century, it housed a succession of petty criminals, including sheep rustlers and, during the Famine, people who committed crimes with the sole aim of being imprisoned there: even the meager rations offered at the jail were better than what was available in other parts of the country. It was a powerful symbol of British rule on the island of Ireland; its residents over the years included the bold Robert Emmet and, of course, it was also the place where the 1916 rebels were taken and executed. Every Dark Hour is a colourful and entertaining telling of the history of the jail and its colourful cast of residents over the years - as well as vivid accounts of the heroic men and women who gave freely of their time and energies to restore the jail to its former grandeur when it was on the verge of being reclaimed by the elements.
