In short: The Genbaku Dome is a haunting survivor of the first atomic bomb used in war. While the city around it was obliterated on August 6, 1945, this former exhibition hall remained standing. Today, it serves as a permanent, preserved ruin and a powerful UNESCO-listed monument to nuclear devastation.

Designed by Czech architect Jan Letzel and completed in 1915, the building originally served as the Hiroshima Prefectural Commercial Exhibition. It stood in a dense business district near the Aioi Bridge, a location chosen as the aimpoint for the atomic bomb due to its visibility. On August 6, 1945, the bomb exploded 600 meters above the ground and 150 meters from the building. Because the blast force was nearly vertical, the structure's earthquake-resistant design allowed its core columns and outer walls to survive, even as everyone inside was killed.

In the postwar years, the ruin became a subject of intense local debate. While some residents advocated for its demolition, others fought to preserve it as a testament to the tragedy. Shinzo Hamai, the first popularly elected mayor of Hiroshima, led the effort to secure funding for its maintenance, even soliciting donations on the streets of Tokyo. In 1966, the Hiroshima City Council officially resolved to preserve the structure indefinitely, and it was later designated a UNESCO World Heritage Site in 1996.

The site's inclusion on the UNESCO list was not without friction. Delegates from China and the United States expressed reservations, with China noting concerns that the monument might obscure the history of Japan's wartime aggression, and the U.S. arguing that the site lacked broader historical context. Despite these objections, the Dome stands today as a focal point for anti-nuclear protests and annual peace ceremonies. It remains a stark, minimal intervention in the landscape, stabilized by internal metal framing to ensure it stays exactly as it appeared in the immediate aftermath of the bombing.
