The Atomic Bomb Dome (原爆ドーム) was originally called the Hiroshima Prefectural Industrial Promotion Hall. It was designed by Jan Letzel, a Czech (Bohemian) architect, and completed in 1915. The three-story building was constructed from brick and reinforced concrete and featured a distinctive curved steel dome, which now remains as an exposed steel frame. Its European architectural style reflected modern design of the era. The hall originally served as an exhibition center to display new products and promote the industrial development of Hiroshima Prefecture.

On August 6, 1945, at 8:15 AM, the building was hit by the atomic bomb “Little Boy.” The hypocenter was only 160 meters away, and the bomb exploded 600 meters above ground. The Atomic Bomb Dome was the only building to remain standing in the immediate area, although all approximately 30 people inside perished instantly.

The Dome was designated a UNESCO World Heritage Site in 1996 for its historical and symbolic significance. It represents hope that humanity will eliminate nuclear weapons and achieve lasting peace. It is also recognized as a universal symbol against war and for global peace advocacy.

The building is preserved in its ruined state according to the wishes of Hiroshima residents, serving as a powerful reminder for future generations. Internal support structures have been added, and the building’s stability is continuously monitored. Conservation efforts are funded through donations from people both within Japan and around the world.

Visitors can view the Atomic Bomb Dome from the outside only. Standing before the ruins offers a strong emotional experience and understanding of the scale of human loss. The site also serves as the starting point for exploring Hiroshima Peace Memorial Park, which houses additional monuments and the Peace Memorial Museum.
