This building was completed in April of 1915 under the design and supervision of Czech architect Jan Letzel, capturing the fancy of citizens of Hiroshima with its characteristic green dome. The atomic bomb exploded at an altitude of 600 meters approximately 160 meters southeast of the Industrial Promotion Hall, instantly killing everyone inside the building which was seriously damaged and completely burned out. In December 1996 this structure was added to the UNESCO World Heritage List as a reminder to the entire world of the horrors of the atomic bomb and a symbol of global peace.
