The Manhattan Project was a massive wartime effort shrouded in complete secrecy – most of the K-25 workers did not even know what they were building!  Their mission: build the first atomic weapon before Nazi Germany and end World War II.  

To ensure victory, secrecy was paramount. No one could know of Oak Ridge. No one could know the purpose of the plants. Isolation was key.

Step back in time and discover the inner workings of the K-25 Plant, meet the people who worked there, and learn about one of the most significant industrial, scientific, an military achievements in American history.
