The rolling hills and narrow valleys of East Tennessee proved to be the ideal location for the top-secret atomic weapons program developed here beginning in 1942. Oak Ridge, Tennessee was home to several massive Manhattan Project facilities employing thousands of workers during and after World War II and was the headquarters for the project after relocating from New York City. These facilities in Oak Ridge operated with one goal in mind: enriching uranium for use in the world’s first atomic bombs.  

Today, Oak Ridge carries on the legacy of those fateful years so long ago. Several highly secured nuclear research facilities still exist in the community and the city is home to a wealth of historic sites that tell the remarkable story of the Manhattan Project and the dawn of the atomic age.
