From here:
The original 1864 cathedral was badly damaged in a major earthquake on February 22, with the bell tower completely destroyed.
A second quake, in June, caused further damage, shattering stained glass panels.
The city has yet to decide on a long-term replacement for the landmark and has commissioned architect Shigeru Ban to create a structure that will be ready by the one-year anniversary of the earthquake and last until the Anglican cathedral can be restored to its original condition.
Tokyo-based Mr Ban has earned a reputation for his use of cardboard – because it is recyclable and surprisingly strong – for large buildings.
It isn’t often such an apt metaphor presents itself: a cardboard cathedral for a denomination with a cardboard faith which will soon have to fill its pews with cardboard cut-out people to maintain the illusion that someone is still interested.
