On July 16, 1945, at 5:29:45am, the first atomic explosion was detonated at Trinity Site in New Mexico, U.S.A. It came less than 50 years after the discovery of radioactivity in 1896 and brought many threads of physics, technology and politics to a dramatic culmination. The man-made thunder that echoed off the Oscuro Mountains continues to reverbrate through the modern world. It was the beginning of mankind's continuing struggle with the nuclear genie.

The purpose of this site is to tell the story of nuclear weapons through historical documents, photos, and videos. In the spirit of Project Gutenberg, the intent is to create an online archive from the large body of U.S. government information about nuclear weapons. For the most part the original documents will be allowed to speak for themselves, with an occasional thread of narrative or clarification if it is helpful.

The High Energy Weapons Archive, maintained by Carey Sublette, is a sister site to this one. It can be found at either of these two mirror locations: High Energy Weapons Archive at Envirolink or the High Energy Weapons Archive at FAS. Carey and I are actively collaborating to provide the broadest variety of nuclear weapon information, in the most convenient form that we can. The two sites each have a different focus. The High Energy Weapon Archive provides current information, technical data, and informative write-ups. This Trinity Site focuses on a historical perspective through reproductions of public domain documents, photos, and videos.
