In 2005, the mayor of Hiroshima, Tadatoshi Akiba, took initiative for the worldwide organization Mayors For Peace, and Narvik was one of the municipalities that joined. Akiba donated a stone from the reputed zero-point field Hiroshima as a gift to Narvik. The stone from Hiroshima was unveiled on august 6th 2006 in conjunction with the new monument “Peace is a Promise of the Future”. Both monuments are placed in the town square of Narvik. “Aldri Mer” means “Never Again” in Norwegian.

Mayors for Peace was founded in June 1982 by then-Mayor of Hiroshima, Takeshi Araki, with the mission of ending the threat of nuclear weapons to our world. It is registered by the United Nations as an NGO with its headquarters in the Hiroshima Peace Culture Foundation building in Peace Memorial Park. As of 2021, Mayors for Peace claimed a membership of 8,054 cities in 165 countries.
