After more than a decade of work, the U.S. Department of Energy and Department of Interior formally established the Manhattan Project National Historical Park on Tuesday. The new park, which includes Oak Ridge, commemorates one of the signature scientific achievements of the 20th century. It was formally established when Interior Secretary Sally Jewell and Energy Secretary Ernest Moniz signed a memorandum of agreement, or MOA, in Washington, D.C.
The unique, three-site Manhattan Project National Historical Park includes Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico. It’s the nation’s 409th park.
The Manhattan Project was a top-secret federal program to build the world’s first atomic bombs during World War II. Here are photos from Tuesday’s signing ceremony, taken by the National Park Service and used with their permission.
