Dublin and Monaghan Bombings

Five ANFO cars detonated across Dublin and Monaghan on 17 May 1974, killing thirty-three people and wounding nearly three hundred within ninety minutes. The Ulster Volunteer Force struck Talbot Street, Parnell Street, Leinster Street and Monaghan town while ordinary citizens worked, shopped or waited for buses. That afternoon remains the deadliest single day of British-based terrorism in Ireland, transforming casual confidence into enduring vigilance.
