The Department of Energy (DOE) owns and manages the federal properties at Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico. Established by Congress in 2015, Manhattan Project National Historical Park (MAPR) is spread across these three locations and co-managed by the DOE and the National Park Service (NPS). A Memorandum of Agreement between the DOE and the NPS specifies the responsibilities of each while laying the groundwork for collaboration. Together, we share the complete story of the Manhattan Project and its legacy.
Featuring landscapes and structures dating back to the early 1940s, MAPR sites in Oak Ridge, Hanford, and Los Alamos allow visitors to explore how atomic weapons changed the world. The preservation and interpretation of the sites is key to the scientific, social, political, and cultural stories of those who ushered in the atomic age.
Los Alamos is home to 30 of these official landmarks. (Additional “park-eligible” sites are continually being identified and evaluated for historic significance.) Some are available to visit year-round, while others are “behind the fence” at Los Alamos National Laboratory and only accessible to the public on guided tours.
