The Spire is an elongated cone, having a diameter of 3m (10 ft) at the base, narrowing to 15cm (6 in) at the top. It was originally intended that the Spire be completed by 2000 in honour of the new millennium, but construction was delayed because of difficulty obtaining planning permission and environmental regulations. The sculpture was bulit on the site of the former Nelson Pillar on O'Connell Street.
