The Atomic Bomb Dome was originally built in 1915 as the Hiroshima Prefectural Industrial Promotion Hall, designed by Czech architect Jan Letzel. On August 6, 1945, the world's first atomic bomb detonated approximately 160 meters away. Because the explosion occurred almost directly overhead, the building did not collapse sideways — the outer walls and steel dome frame survived. After the war, the ruins were designated for permanent preservation, and in 1996 they were inscribed on the UNESCO World Heritage List. The dome now draws over 3 million visitors annually as a symbol of nuclear abolition and world peace.

UNESCO World Heritage Site & Symbol of Nuclear Abolition
Designated a UNESCO World Heritage Site in 1996, this "negative heritage" serves as a universal symbol of the catastrophic impact of nuclear weapons and a call for world peace.
Walls and Dome Framework That Miraculously Survived
Because the bomb detonated almost directly overhead, the building escaped total collapse. The exposed steel dome frame and outer walls remain as they were, bearing direct witness to the bomb's power.
Iconic View Across the Motoyasu River
The view of the dome framed through the Memorial Cenotaph is one of Hiroshima's defining vistas. The dome reflected in the river, especially during the evening light-up, moves many visitors deeply.
Gateway to Peace Memorial Park
Adjacent to Peace Memorial Park, the dome can be visited alongside the Memorial Cenotaph, the Peace Museum, and the Children's Peace Monument — an ideal starting point for Hiroshima's peace-themed attractions.

What to See
1The Dome Frame and Outer Walls — Silent Witnesses
The defining feature of the Atomic Bomb Dome is the outer wall and brick structure preserved exactly as they appeared after the bombing. The exposed steel skeleton speaks wordlessly about the destructive force of heat, blast, and radiation. Walk around the full perimeter and observe from every angle.
2Aligned with the Memorial Cenotaph — Peace in Architecture
Peace Memorial Park's Memorial Cenotaph, the Flame of Peace, and the Atomic Bomb Dome are arranged on a single axis by design. The view of the dome through the cenotaph arch is Hiroshima's most iconic image — architect Kenzo Tange's deliberate choice to embed a lasting peace message into the city's landscape. The cenotaph inscription "Rest in Peace, for the mistake shall not be repeated" invites quiet reflection.
3The Night Light-Up — A Haunting Glow
After sunset the dome is lit up, revealing a strikingly different atmosphere from daytime. Around August 6, Peace Memorial Day, the Motoyasu River comes alive with floating lanterns (Toro Nagashi), creating an unforgettable nightscape. Combining an evening visit with the lantern ceremony is one of Hiroshima's most moving experiences.
