TLDRThe Hiroshima Peace Memorial, known as the Genbaku Dome, is a poignant remnant of the first atomic bomb dropped on August 6, 1945, by the American B-29 Superfortress, nicknamed 'Little Boy.' This bomb instantly claimed a quarter of Hiroshima's population, with over 70,000 deaths, and flattened nearly 5 square miles of the city. Miraculously, the Prefectural Industrial Promotion Hall, now the Genbaku Dome, remained standing despite being only 490 feet from the hypocenter. Its survival is attributed to its sturdy construction and the bomb's high-altitude detonation, which directed the blast downward. After much debate, the building was preserved as a symbol of peace and a reminder of nuclear warfare's devastating consequences. In 1996, it was designated a UNESCO World Heritage Site, standing as a stark testament to the destructive power of nuclear weapons and the tragic loss of an estimated 140,000 lives.
