Dome de la Bombe atomique

**Viewing perspectives:** The dome is best appreciated from multiple angles to understand its architectural skeleton. The north riverbank (Motoyasu River side) provides the classic frontal view, showcasing the dome's silhouette against the sky — ideal for photography, especially at sunrise (eastern light) or sunset (golden hour backlighting). The south side, within Peace Memorial Park, offers close-range observation of the building's shattered walls and exposed steel beams. For historical context, view from the T-shaped Aioi Bridge (the bomb's original target, though it missed by 240 meters and detonated over Shima Hospital) to understand the bomber's perspective. **Preservation details:** The dome's conservation involves delicate balance — stabilizing decay without restoration that would erase authentic damage. Steel reinforcements were added internally in the 1960s, 1989, and 2002 to prevent collapse, and bricks are treated with protective coatings against weathering. However, no reconstruction of missing walls, roof, or dome copper sheathing occurs; the structure remains frozen in its August 6, 1945 state. Close observation reveals details: melted glass fragments embedded in walls, blast-twisted steel beams, and shadow patterns from intense thermal radiation. Information plaques (Japanese/English) around the perimeter explain these forensic details. **Historical context signs:** Surrounding the dome, markers identify the hypocenter location (Shima Hospital, 160m southeast, now a commemorative plaque), the estimated 3,000–4,000°C ground temperature at detonation, and the blast's immediate 2km total-destruction radius. Reading these signs before viewing the dome enhances comprehension of the weapon's scale — that this building survived at all, so close to the hypocenter, is due solely to the near-vertical blast direction which compressed rather than laterally obliterated the structure.
