Building The Bomb: Extremely rare access to the Nevada test site for nuclear weapons. From 1951, over four decades, the US government carried out almost a thousand nuclear tests at this test site, earning it the nickname of the “most bombed place on Earth”. Here, they took the crude nuclear weapons that had been dropped over Hiroshima and Nagasaki in 1945 and honed their destructive power. A hundred of these tests, known as atmospheric shots, took place above ground, creating the characteristic mushroom clouds that have become synonymous with nuclear detonations. The government still carries out classified work on the site, and access is limited to a small number of carefully vetted visitors each year, who are not allowed to take photographs.
