Nagasaki
Hiroshima was the first to be bombed in World War 2.
the first atomic bomb leveled nothing. That was exploded at the Trinity test site. The first bomb used in war was at Hiroshima Japan, and pretty much destroyed everything in a 3 mile radius. That is just over 7 square miles.
The Gadget was tested at Trinity site in NM, near the northeast corner of what is now White Sands Missile Range.
The first atomic bomb was set off northwest of Alamogordo, New Mexico inside what is now White Sands Missile Range on July 16, 1945. If you want to, the site is open for public tours twice a year on the first saturdays of April and October.
