Spire of Dublin

The Spire of Dublin, officially titled the Monument of Light, is a stainless steel, pin-like monument 390 ft. tall, located on the site of the former Nelson’s Pillar on O'Connell Street in Dublin. The spire is an elongated cone 9.8 ft. in diameter at the base, narrowing to 6 inches at the top. It is constructed from eight hollow tubes of stainless steel and features a tuned mass damper to counteract sway.

In 1966 Nelson's Pillar, which had stood prominently on O’Connell Street, was destroyed in a bombing by former IRA members. In the 1990s, plans were launched to improve the street scape, and the centerpiece of this regeneration was to be a replacement monument for Nelson's Pillar, a 134-ft tall monument installed in 1808. The Spire of Dublin design was chosen through an international competition.
