About the location (from here):
Chalice is a permanent sculpture located in Christchurch’s Cathedral Square. Chalice celebrates the new millennium and the 150th Anniversary of the founding of Christchurch and Canterbury by the Canterbury Association. Sculptor Neil Dawson was commissioned to produce a major contemporary, public artwork for Christchurch by The Turning Point 2000 Trust. The official lighting ceremony was held 10 September 2001 and Chalice will be lit at night with one floodlight situated inside the base of the cone and one spotlight aimed at the exterior of the structure from the pavement.

Chalice has a primary hexagonal steel structure and a solid steel conical base. Native leaf patterns are cut from aluminium sheet, welded to custom-made triangular beam structures, and then bolted into position on the frame. The exterior of the conical structure is painted silver using a durable automotive paint. The interior of the sculpture, seen through the perforated shell, is painted metallic blue. A dark band of black pearl granite in six segments surrounds the foot of Chalice making a circle just over 3 metres in diameter. 18 metres high, 2 metres in diameter at ground level and 8.5 metres in diameter at the top, its shape mirrors the spire of Christchurch Cathedral.
