Trinity was the code name given to the nuclear test that saw the first detonation of a nuclear weapon. The code name was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, after a poem by John Donne. It was conducted on July 16, 1945, as part of the Manhattan Project on the Alamogordo Bombing and Gunnery Range in the Jornada del Muerto desert. The test used a Fat Man bomb of the same design as that detonated over Nagasaki. The complex design of the implosion-type nuclear weapon required a major effort from the Los Alamos Laboratory, and testing was required to allay fears that it would not work. Its detonation (video featured) produced the explosive power of about 20 kilotons of TNT (84 terajoules). The test site is now part of the White Sands Missile Range. It was declared a National Historic Landmark District in 1965, and listed on the National Register of Historic Places the following year.
