On August 6, 1952, seven years after the bombing of Hiroshima, five war orphans unveiled the cenotaph for the victims of the A-bomb blast. It is known as the Memorial Monument for Hiroshima, City of Peace. Approximately 1,000 persons attended the unveiling ceremony. Each year, on August 6, the memorial service is held in front of this monument located in the Peace Memorial Park. In this photo from 1952, one can still see private houses that had been rebuilt after the war in the area that is now the Peace Park.
