The Spire of Dublin, also called the Monument of Light, stands on O'Connell Street on the site of the former Nelson's Pillar. Ian Ritchie Architects designed it, with Arup as engineer, for Dublin City Council. The first section went up on December 18, 2002 and it was completed on January 21, 2003. The article names no architectural style and calls it a pin-like monument.
It is stainless steel, built from eight hollow cone sections. The spire is 120 meters (394 feet) tall, 3 meters wide at the base and 15 centimeters at the top, and weighs 133.15 tonnes. Two tuned mass dampers counter sway. The base pattern draws on a rock core sample and the DNA double helix.
The top 10 meters are lit by LEDs shining through 11,884 holes. It cost €4.6 million. It is an open street monument, though the article gives no access details.
