The Spire of Dublin, officially called the Monument of Light (An Túr Solais in the Irish language) is a tall, stainless steel, needle-like monument 121.2 metres (398 ft) in height, located in O'Connell Street Dublin on the site of the former Nelson's Pillar.
The spire was designed by Ian Ritchie Architects, who sought an "Elegant and dynamic simplicity bridging art and technology". The contract was awarded to SIAC-Radley JV and it was manufactured by Radley Engineering of Dungarvan, Co. Waterford, and erected by SIAC Construction Ltd. The first section was installed on 18 December 2002.
Five additional 20m sections were added with the last one installed on 21 January 2003. The spire is an elongated cone of diameter 3 m (9.8 ft) at the base, narrowing to 15 cm (5.9 in) at the top. Construction of the world's tallest sculpture was delayed because of difficulty in obtaining planning permission as well as issues with environmental regulations.
It is constructed from eight hollow tubes of stainless steel and features a tuned mass damper, designed by engineers Arup, to counteract sway. The steel underwent shot peening to allow it subtly reflect the light falling on the surface, while the metal also changes colour due to its reflective properties.
The Spire of Dublin is a short walk from the Trinity City Hotel, just across the River Liffey, via O'Connell Bridge. Why not plan your trip to Dublin by checking our latest special offers.
