Manhattan Project National Historical Park
Manhattan Project National Historical Park is a United States National Historical Park that honors the work and sites of the Manhattan Project. It is run by two agencies: the National Park Service and the Department of Energy. The park has three units: Oak Ridge, Tennessee; Los Alamos, New Mexico; and Hanford, Washington.
The park was officially established on November 10, 2015, after years of planning and negotiation between the two agencies. The Department of Energy owns and manages most of the properties, while the National Park Service provides interpretation, visitor centers, and park rangers. Not all buildings are open to the public, and some areas can only be visited via special tours.
The Los Alamos Visitor Center is at 475 20th Street in downtown Los Alamos and is open Friday through Monday from 10 a.m. to 3 p.m.
Three areas of the park on Los Alamos National Laboratory property are open to the public only through Department of Energy–organized bus tours.
In Oak Ridge, the American Museum of Science and Energy offers bus tours of several Clinton Engineer Works buildings, and the Oak Ridge History Museum explores the social impact of the Manhattan Project on the local community.
