When the first atomic bomb was dropped over Hiroshima on August 6, 1945, the city became known worldwide for this unenviable distinction. After the war, great efforts were taken to rebuild the city. Destroyed monuments of Hiroshima’s historical heritage, like Hiroshima Castle and Shukkeien Garden, were reconstructed. In the center of the city a large park was built and given a name that would reflect the aspirations of the re-born city: Peace Memorial Park. It is also home to Mazda Museum.
