The Last Nuclear Bomb Memorial in Hiroshima reimagines the memorial square as a layered landscape of remembrance, healing, and community. An inner sunken layer offers solemn spaces for sacrifice, meditation, and gathering; a middle layer supports rest and communication; and an outer ecological belt restores vegetation. Circular paths and radial routes unify the site, where memory and daily life coexist, urging visitors to mourn the past, cherish peace, and envision a world without war.
