a-bomb dome
When the nuclear bomb named Little Boy hit Hiroshima on August 6, 1945, one of the very few buildings left standing in the city was the Hiroshima Prefectural Industrial Promotion Hall, built in 1915 by a Czech architect. The ruin of this otherwise not very noteworthy building became a symbol of the city's destruction. It was never torn down and became known as the A-Bomb Dome.
At night especially, its ghostly green and orange lighting serves as a dramatic reminder of the incredible devastation of the world's first nuclear attack.
