This collection is composed of 7 roof tiles and stones from ground zero at Hiroshima as well as supporting materials related to the these items and pamphlets from Hiroshima University. From the supporting materials we know that these tiles were collected from the rivers in Hiroshima and that it is believed that these stones contain the souls of individuals whose lives were taken from them as a result of the atomic bombing of Hiroshima on August 6, 1945. These items were shared with us in the hopes that they would serve as a reminder of the devastation and continued impact of the bombing on the Japanese people.
