Manhattan Project National Historical Park

Innovation that Changed the World

Oak Ridge, TN was instrumental in the United States win over Nazi Germany during WWII because of the development of the atomic bomb. Known as the “Secret City”, Oak Ridge was not on any maps and 100,000 workers were brought to the city to work on a Top Secret war project, known as the Manhattan Project.

The Manhattan Project is the story of generals, physicists, chemists, mathematicians, engineers, brought together to broaden the limits of human knowledge and technological achievements in ways never before imagined. It is also the story of death and destruction associated with WWII, and a new weapon capable of unimagined levels of devastation, produced by workers who had no idea they were working on the device that would end the war.

More about the Project

The Manhattan Project National Park consists of 3 cities; Oak Ridge, TN-Los Alamos, NM- Hanford, WA. The National Park is designed to educate the public and interpret what some have called “the single most significant event of the 20th century,” the development of the atomic bomb and introduction of the Nuclear Age.

The Manhattan Project National Historical Park consists of three sites located in Oak Ridge, Tennessee; Los Alamos, New Mexico; and Hanford, Washington.  Newly opened in 2015, this historic park features sites, facilities, equipment, and artifacts associated with an unprecedented top-secret government program known as the Manhattan Project.  The project enabled the U.S. to develop the atomic weapons that brought an end to World War II. The legacy of the Manhattan Project is seen in many areas such as space travel, nuclear medicine, and energy production to name a few.  The Manhattan Project National Historical Park tells the stories of people, events, science, and engineering that changed the world.
