On the morning of 28 June 1922, Dubliners woke to the sound of the National Army shelling the Four Courts, Headquarters of the anti-Treaty IRA Executive. Three days later, the garrison surrendered - the Four Courts lay in ruins, the Public Records Office was destroyed. Historian Liz Gillis will discuss the opening battle (for the capital city) of the Irish Civil War. It was eight days of a war that lasted eleven months but which affected this country for generations.
