A-Bomb Dome: Complete Visitor Guide
The Hiroshima Peace Memorial, known as the A-Bomb Dome (Genbaku Dome), stands in Hiroshima Peace Memorial Park on the Ōta River delta, at the edge of the ground once directly beneath the atomic bombing of 6 August 1945. It is a place of remembrance, not a sightseeing attraction, and it asks visitors for a quiet, reflective register rather than a casual one.
Visiting: hours, cost and how to approach it
The Dome is viewed from outside a fenced perimeter and there is no admission charge to see it; it sits a short walk from Hiroshima Station by tram, within the Peace Memorial Park. The park itself is open around the clock, though the adjoining Peace Memorial Museum keeps set hours (roughly 7:30am to 7pm most of the year, shorter in winter, extended in August), with its first and last entry slots typically requiring advance online booking. Most visitors pair a walk past the Dome with time at the Cenotaph, the Flame of Peace, and the Children’s Peace Monument nearby, then the Museum itself, allowing at least half a day for the full park and museum together. Photograph the Dome respectfully, from the designated viewing areas, without treating it as a backdrop.
What happened here
At 8:15am on 6 August 1945, a US B-29 dropped the uranium bomb known as “Little Boy,” which detonated roughly 600 meters above the city, the first use of a nuclear weapon in war. Casualty figures vary by source and by what is counted: contemporary 1945 tallies recorded roughly 66,000 killed outright, while later estimates put total deaths by the end of that year as high as 140,000, out of a wartime population near 350,000; around 90 percent of the dead were civilians. Survivors of the bombing are known as hibakusha.
Why this particular ruin survived
Before the bombing, the building was the Hiroshima Prefectural Commercial Exhibition Hall, renamed the Industrial Promotion Hall in 1933 and designed by the Czech architect Jan Letzel, completed in 1915. It stood almost directly beneath the blast, and its steel-reinforced, earthquake-resistant structure and vertical columns let its skeletal frame keep its shape when almost everything around it was destroyed. Rather than clear the site, Hiroshima’s city council formally voted in 1966 to preserve the ruin exactly as the bombing left it, with major restoration completed the following year and further structural stabilization carried out through 1990.
The UNESCO listing, explained
The building is inscribed on the UNESCO World Heritage List as the Hiroshima Peace Memorial (Genbaku Dome), added in December 1996. UNESCO’s citation frames it as a symbol both of the destructive power of nuclear weapons and of humanity’s hope for lasting peace and the abolition of such weapons. Within Peace Memorial Park, the nearby Cenotaph’s epitaph reads, “Please rest in peace, for the error shall not be repeated,” a phrase deliberately left without a named subject, read as a shared, collective pledge rather than an apology assigned to any one nation.
Nearby, and how it fits into a visit
The Peace Memorial Museum, whose Main Building reopened in 2019 after seismic retrofitting, holds the personal belongings, photographs and testimony that give the bombing’s toll a human scale; it is a difficult but widely considered essential visit alongside the Dome itself. The Children’s Peace Monument, honoring Sadako Sasaki and the origin of Hiroshima’s paper-crane tradition, and the National Peace Memorial Hall, an underground remembrance space, both sit within a short walk. Each 6 August, the city holds a memorial ceremony at 8:15am, the exact moment of the bombing, followed that evening by a lantern-floating ceremony on the Motoyasu River.

One practical note worth carrying with you: allow a full, unrushed morning for the Dome, the park’s memorials and the Museum together, since compressing it into a quick stop does a disservice to what the site is asking of you.
