Start with our Visitor Center

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 bomb. 

Today 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. Drop by our visitor to speak with park rangers, stamp your passport book, pick up a junior ranger book, and learn about ranger programs. Then use our park app to discover places in Oak Ridge related to the Manhattan Project.

Basic Information

We offer a traditional passport stamp as well as a unique three-part stamp. Travel to our visitor centers in Los Alamos, Oak Ridge, and the Tri-Cities to receive one-third of a stamp. When all three pieces are put together, they make a whole stamp.
