Christchurch's city square stands at the heart of the rebuilding efforts, with the remains of Christ Church Cathedral emblematic of what has been lost. The February 2011 earthquake brought down the 63m-high spire, while subsequent earthquakes in June 2011 and December 2011 destroyed the prized stained-glass rose window. Other heritage buildings around the square were also badly damaged, but one modern landmark left unscathed is the 18m-high metal sculpture Chalice, designed by Neil Dawson. It was erected in 2001 to commemorate the new millennium.
The much-loved Gothic cathedral has been at the centre of a battle between those who seek to preserve what remains of Christchurch's heritage, the fiscal pragmatists, and those ideologically inclined to things new. In 2012 the Anglican Diocese announced that the cathedral was to be demolished, but work was stayed when heritage advocates launched court proceedings. Eventually, in September 2017, the church leadership voted to preserve the building after the government and Christchurch City Council banded together to offer significant financial support. It's thought that the rebuild could take up to 10 years, with an estimated cost of $104 million.
