This “Secret City” once housed more than 75,000 people at the peak of the Manhattan Project, the top-secret mission to develop the atomic bomb. People in neighboring towns had no idea that the town even existed. Every resident over 12 wore a badge at all times, and no visitors were allowed without prior approval. Military police manned the gates, and guardhouses were set up along the fence line surrounding the site; three remain today. Stop along the way for great photo ops or visit one of two replicas at the American Museum of Science & Energy (point 11) or the Children’'s Museum of Oak Ridge (point 15).
