The Hiroshima Atomic Bomb had been dropped for the first time in the history of humankind on 8AM 15Min, August 6, 1945, which exploded over Hiroshima City.
In September 1949, "the A-bomb Reference Material Display Room" was established in the Hiroshima City Central Community Center. This was the start of the public display of atomic bomb materials. Under the "Hiroshima Peace Memorial City Construction Law," which was promulgated that year, the Peace Memorial Hall was opened in June 1955 and the Peace Memorial Museum in August 1955, in Peace Memorial Park. In June 1994, to improve display and collection functions and provide more space for peace education, Peace Memorial Hall was renovated and integrated into the Peace Memorial Museum. The two facilities are now open as a renewed Hiroshima Peace Memorial Museum on April 25, 2019.
On July 5, 2006, the Main Building of the Peace Memorial Museum was designated one of the important cultural assets of Japan. This is the first cultural asset from among buildings constructed in the post war period.
