Manhattan Project National Historical Park

For over a decade, the Department of Energy and National Park Service, in cooperation with other Federal agencies, state and local governments, and other stakeholders, pursued the possibility of including the Department’s most significant Manhattan Project properties within a Manhattan Project National Historical Park (MAPR). After numerous studies and several draft bills, Congress passed the National Defense Authorization Act of 2015, which included provisions authorizing the Park to be located at three sites: Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico. President Obama signed the National Defense Authorization Act into law on December 19, 2014.

On November 10, 2015, Secretary of the Interior Sally Jewell and Secretary of Energy Ernest Moniz signed the Memorandum of Agreement between the two agencies defining the respective roles in creating and managing the park. The agreement  included provisions for enhanced public access, management, interpretation, and historic preservation. With the signing, the Manhattan Project National Historical Park officially was established.
