Every year on 6th August, a ceremony is held in the Hiroshima Peace Memorial Park with the objective to console the victims of the atomic bombing and to facilitate world peace. Thousands of people including the representatives from all over the world, assemble to pray for the realization of a lasting world peace. The ceremony is a brief one and lasts only 45 minutes. The Peace Declaration is read out by the Mayor of the city of Hiroshima and sent to every country in the World.
An arch-shaped cenotaph was built in 1952 where the register having the names of the victims has been kept. The characters meaning "Let all the souls here rest in peace, for we shall not repeat this evil" are carved on the front of the stone coffin in the cenotaph. One can see the cenotaph, the A-bomb dome and the peace memorial museum in alignment.
Sadako Sasaki, who was exposed to the bombing at age two, contracted leukemia ten years later and died. Shocked by her death, her classmates put out a national call to "build a monument to mourn all the children who died from the atomic bombing." This nine meter high monument has been built with the support of students in more than 3,100 schools around Japan and in nine other countries. On the top of the three-legged pedestal stands the bronze figure of a girl holding up a gold-colored "folded" crane. On opposite sides of the pedestal are suspended boy and girl sculptures symbolizing a bright future and hope. On the stone underneath the pedestal is inscribed, "This is our cry. This is our prayer. For building peace in this world." (source)
The former 'Hiroshima prefectural commercial exhibition hall' which withstood the bombing is popularly known as 'A-bomb dome'. The building has been kept as a reminder of the horrors of war.
