A further such memorial is being carefully dismantled in central Oslo. The area outside the cathedral has become a makeshift shrine to those killed in the terrorist attacks of 22nd July. The flowers and other organic material will be composted and the wax from the candles recycled. But the messages and mementos are to be preserved in the national archive.
A similar process of preservation and documentation has taken place at the Vietnam Veterans Memorial in Washington DC. Artefacts left there continue to be gathered up and safeguarded to become part of a living and very public collection.
This will also be the case in Norway. Those traces of collective grief left on a street in central Oslo are destined to become sources of collective memory.
