The Spire of Dublin, alternatively titled the Monument of Light[1] (Irish: An Túr Solais),[2] is a large, stainless steel, pin-like monument 120 metres (390 ft) in height,[3] located on the site of the former Nelson’s Pillar on O’Connell Street in Dublin, Ireland.

The monument was commissioned as part of a street layout redesign in 1999. O’Connell Street had declined for a number of reasons such as the proliferation of fast food restaurants and the opening of bargain shops using cheap plastic shop fronts which were unattractive and obtrusive; the existence of derelict sites; and the destruction in 1966 of Nelson’s Pillar following a bombing by former IRA members.
