HIROSHIMA: This commercial exposition hall was the only reinforced concrete structure at ground zero, and was left standing after the dropping of the atomic bomb. It has become a symbol of the bombing, and has actually been "restored" to keep it in the precise state of ruin it was in 1945. Just to the right of the dome is visible a bank of lights for the adjacent baseball stadium. Hiroshima is a very modern city. May 17, 1998
