The skeletal dome of the former Hiroshima Prefectural Industrial Promotion Hall, the only structure near the atomic bomb's hypocenter to survive the blast. Designated UNESCO World Heritage Site in 1996, it stands as the world's most powerful symbol of nuclear destruction and peace advocacy.
The Hiroshima Peace Memorial, known internationally as the Genbaku Dome or A-Bomb Dome, is the only structure near the hypocenter of the atomic bomb dropped on Hiroshima on August 6, 1945 to survive in recognizable form. The building was originally constructed in 1915 as the Hiroshima Prefectural Industrial Promotion Hall, a European-style domed structure designed by Czech architect Jan Letzel. When the bomb detonated approximately 600 meters above the city at 8:15 AM, the near-vertical blast largely preserved the building's external shell while destroying virtually everything inside and killing all occupants instantly. The skeletal dome and partially collapsed walls remained standing while the surrounding city was flattened within a 2-kilometer radius. After postwar debates over demolition or preservation, Hiroshima city council resolved in 1966 to maintain the structure permanently as a testament to the atomic bombing. Extensive structural stabilization and reinforcement works have been carried out periodically since the 1960s to prevent further deterioration of the concrete, brick, and steel frame. Designated a UNESCO World Heritage Site in 1996 — the only such site nominated over the stated objections of permanent UN Security Council members — the dome stands at the northern tip of Peace Memorial Park, visible from the park's central axis and framed by the Motoyasu River. The site is free to visit at any hour. An explanatory monument nearby provides historical context in English and Japanese. The dome is most powerfully experienced in conjunction with the nearby Hiroshima Peace Memorial Museum, which provides detailed documentation of the bomb's effects and personal testimonies from survivors.
Why it matters
The Genbaku Dome is the only structure near the atomic bomb's hypocenter to survive the 1945 Hiroshima blast and stands as the world's most immediate physical witness to nuclear warfare, designated UNESCO World Heritage Site in 1996 as a permanent monument to the abolition of nuclear weapons.
