This section features information about the three primary sites, Hanford, WA, Los Alamos, NM, and Oak Ridge, TN, along with many of the other sites around the country, from Dayton, OH, where the polonium trigger for the bomb was designed, to Chicago, IL, where the world’s first sustained nuclear reaction took place.
Danish physicist Niels Bohr had observed that building an atomic bomb could never be done without turning the United States into one huge factory. Bohr saw his words borne out as the nationwide project transformed America with facilities coast-to-coast.
Hanford, Los Alamos, and Oak Ridge are units of the Manhattan Project National Historical Park. Eventually, other Manhattan Project sites such as the Trinity Site and Wendover Airfield may become associated areas.
