On this day in 1974, Dublin City Center was devastated by three large bombs that went off without warning in the span of about 90 seconds. They exploded in the middle of rush hour during a public transportation strike which had left more people in the area than usual. Injuries and casualties were astronomical. When a similar bomb exploded without warning in the city of Monaghan ninety minutes later, the incident became the worst and largest loss of life in Ireland’s more recent troubled history. The explosions injured nearly three hundred people and killed thirty-three civilians in all and forty-three years later, despite multiple investigations, reports, and a mountain of evidence, no one has ever been charged or prosecuted for these attacks.
