The A-bomb Dome is the ruins of the former Hiroshima Prefecture Industrial Promotion Hall which was destroyed by the first atomic bomb ever to be used in the history of mankind on 6 Aug 1945. The atomic bomb was detonated in the air at an altitude of approximately 600 meters almost right over the hall. The explosion by a single bomb claimed the lives of over 200,000 people and the city area within a radius of 2km was turned into ashes. In order to have this tragic feat known to succeeding generations and to make it a lesson for humankind, the reinforcement work of the ruins has been done by the contributions of many people who desire peace within and out of the country. The ruins shall be preserved forever. - 6 Aug 1967 Hiroshima
