But nature had other plans.
Today, over six decades after the atomic bomb, Hiroshima is a green and vibrant modern city.
Though broken and badly charred, they survived and soon were healthy again.
Today, they are officially registered as A-bombed trees.
According to the City of Hiroshima, there are about 170 survivor trees representing 32 different species.
The tree closest to the hypocenter is a Weeping Willow, which stands 370 meters away from the blast.
Another Weeping Willow stands near Seishonen and the Baseball Stadium, 450 meters away from ground zero.

One of the two pillars of the Sanno Shrine Torii was toppled by the A-bomb blast.
