This is the Temple for Christchurch. It can be seen at Peterborough Street in the central city (where the convention centre used to be opposite the town hall).
The Temple is a temporary art installation where people can write about their experiences of the earthquakes, or their hopes for the future of Christchurch. The temple will be moved to Motukarara Racecourse where it will be burned (in the tradition of the Burning Man Festival of art in Nevada). The negative experiences from the earthquake will be released when burned by the fire.
I read quite a lot of what was written on the walls of the temple, and by far this was my favourite sentiment.
