What Travellers Say
Reviews Summary
Visitors find Oak Ridge's Manhattan Project sites historically significant but note the dispersed nature and limited on-site interpretation. While some feel the visitor experience could be more robust, the informative rangers and the importance of the history are consistently praised. The connection to the AMSE museum is a common starting point for understanding the park.
"Not a lot here. But it’s an important stop. The guide in this office is your best asset to finding a strategic plan for your trip to Oak Ridge. The National Park sites are scattered around town and you will be well served talking to the Ranger. Don’t forget to do the Jr Ranger program and remember this is part of a special three part National Park project spread across the US."
Eric Stahl
"Two very helpful and informative chaps who gave us maps and suggestions on what to see with the time we had available. This is inside the children's museum and to see the Oak Ridge portion you are required to pay the entry fee for both museums."
Kimberly McJunkin
"This visor center is basically a table with some minor information. We got our passport stamp and left. It’s very much a disappointment for what it is. For a project that won us World War 2. I really think there should be more. That being said though. It is connected to a children’s museum. That will tell you all about it for a small fee."

The 'Secret City' Revealed
Today, the Manhattan Project National Historical Park Oak Ridge preserves and interprets this vital chapter of American history. The park is not a single, contiguous site but rather a collection of historic areas and facilities scattered throughout the city. Understanding this dispersed nature is crucial for planning a visit.
Visitors can explore remnants of the massive industrial complexes that produced the enriched uranium needed for the atomic bombs, learn about the scientific and engineering challenges overcome, and hear the personal stories of the people who lived and worked here under intense secrecy. The park aims to educate the public about the scientific achievements, the ethical considerations, and the lasting impact of the Manhattan Project.
