The Spire of Dublin, the monument of light

The Spire of Dublin – An Túr Solais

The Spire of Dublin, alternatively titled the Monument of Light (Irish: An Túr Solais), is a large, stainless steel, pin-like monument 120 metres (390 ft) in height located on the site of the former Nelson’s Pillar on O’Connell Street in Dublin, Ireland. It is less than a 10-minute walk away from the Dublin Citi Hotel.


Designed by Ian Ritchie Architects, who sought an “Elegant and dynamic simplicity bridging art and technology”.

The first section, installed on 18 December 2002. Furthermore, the construction of the sculpture delayed because of the difficulty in obtaining planning permission and environmental regulations. The Spire consists of eight hollow stainless steel cone sections, the longest being 20 m (66 ft), installed on 21 January 2003.

It is an elongated cone of diameter 3 m (9.8 ft) at the base, narrowing to 15 cm (5.9 in) at the top. It features two tuned mass dampers, designed by engineers Arup, to counteract sway. The steel underwent shot peening to alter the quality of light reflected from it.

The pattern around the base of the Spire is based on a core sample of rock formation taken from the ground where the spire stands and the DNA double helix. The pattern applied by bead blasting the steel through rubber stencil masks whose patterns created by water jet cutting based on core sample drawings supplied by the contractor.

The design around the 10 m (33 ft) lower part of the Spire created by the architects making a 3D pattern model combining the core sample and double helix and then digitally translated to a 2D image drawing supplied to the contractor and used by specialists for cutting the masking material.

At dusk, the base of the monument lit and the top 10 m (33 ft) and illuminated through 11,884 holes through which light-emitting diodes shine.

The Spire is approximately 15cm in diameter at its apex. Additionally, the upper part of the Spire sways gently when the wind blows, reflecting the character of the city’s climate.

The monument’s tip can sway up to a maximum of 1.5m under extreme wind loading; however, no need to alarm. If you’re nearby when this happens, all tall, slender structures move in the wind, even lamp posts!
