Manhattan Project National Historical Park is a United States National Historical Park commemorating the Manhattan Project that is run jointly by the National Park Service and Department of Energy. The park consists of three units: one in Oak Ridge, Tennessee, one in Los Alamos, New Mexico and one in Hanford, Washington. It was established on November 10, 2015 when Secretary of the Interior Sally Jewell and Secretary of Energy Ernest Moniz signed the memorandum of agreement that defined the roles that the two agencies had when managing the park.[1][2]

The Department of Energy had owned and managed most of the properties located within the three different sites. For over ten years, the DoE worked with the National Park Service and federal, state and local governments and agencies with the intention of turning places of importance into a National Historical Park. After several years of surveying the three sites and five other possible alternatives, the two agencies officially recommended a historical park be established in Hanford, Los Alamos and Oak Ridge.

The Department of Energy would continue to manage and own the sites while the National Park Service would provide interpretive services, visitor centers and park rangers. After two unsuccessful attempts at passing a bill in Congress authorizing the park in 2012 and 2013, the House and Senate ultimately passed the bill in December 2014, with President Obama signing the National Defense Authorization Act shortly thereafter which authorized the Manhattan Project National Historical Park.[3][4]

Visitors can learn about the Manhattan Project and related sites in the vicinity.

There are three areas of the park located on Los Alamos National Laboratory property. These locations are only open to the public by special bus tours organized by the Department of Energy:
