The Hiroshima Peace Memorial, originally the Hiroshima Prefectural Industrial Promotion Hall, and now commonly called the Genbaku Dome, Atomic Bomb Dome or A-Bomb Dome, is part of the Hiroshima Peace Memorial Park in Hiroshima, Japan and was designated a UNESCO World Heritage Site in 1996. The ruin of the hall serves as a memorial to the people who were killed in the atomic bombing of Hiroshima on 6 August 1945. Over 70,000 people were killed instantly, and another 70,000 suffered fatal injuries from the radiation. (https://en.wikipedia.org/wiki/Hiroshima_Peace_Memorial)
