The Hiroshima Atomic Bomb Hypocenter Monument marks the exact ground point directly beneath the airburst of the 'Little Boy' atomic bomb on August 6, 1945. It is situated in the Shima Hospital area, the site of the medical facility destroyed instantly by the explosion. The site features a simple, black stone pillar that serves as a terrestrial coordinate for the blast. It is distinct from the Hiroshima Peace Memorial Park, located a short distance away. The monument provides a stark, localized perspective on the intensity of the nuclear event. It is permanently accessible as an outdoor memorial site.
Directly in front of the stone pillar to capture the marker and the surrounding street context.
Combine this visit with the nearby Peace Memorial Museum for a comprehensive historical context.
The location is compact; expect to spend less time here than at the major memorial parks.
