Registration Deadline: Jun 12, 2025; Submission Deadline: Dec 15, 2025
With the future in such a state of uncertainty and political relationships more strained than ever, there is one silent threat that could prove more deadly and dangerous to humanity than a hundred pandemics: nuclear weapons.
In 1945, the United States bombed Hiroshima and Nagasaki, effectively ending World War II and killing well over 100,000 people, the majority of whom were civilians. The bombing of Nagasaki was the second and final time a country deployed a nuclear weapon in combat. However, it was not the last nuclear explosion, as controlled testing continued for many years.
On the 75th anniversary of the bombing, Nagasaki Mayor Tomihisa Taue called on Japanese President Shinzo Abe and the central government to sign and ratify the 2017 United Nations Treaty on the Prohibition of Nuclear Weapons. However, little, if any, official progress toward an international ban on nuclear weapons has been made since then.
We continue to support the call for a ban on nuclear weapons. As the threat of nuclear bombs remains ever-present, we are launching the sixth edition of our annual architecture competition: The Last Nuclear Bomb Memorial / Edition #6.
The Last Nuclear Bomb Memorial / Edition #6 invites participants to design a memorial located within a decommissioned nuclear weapons testing site. In response to the ongoing global silence surrounding the issue of nuclear weapons, participants must submit their designs with NO DESCRIPTION TEXT. The architectural ideas must be communicated solely through visuals. We challenge participants to design a building or structure where the architecture itself tells the story.
