Nelson's Pillar (also known as the Nelson Pillar or simply the Pillar) was a large granite column capped by a statue of Horatio Nelson, built in the centre of what was then Sackville Street (later renamed O'Connell Street) in Dublin, Ireland. Completed in 1809 when Ireland was part of the United Kingdom, it survived until March 1966, when it was severely damaged by explosives planted by Irish republicans. Its remnants were later destroyed by the Irish Army.
