On May 1, U.S. Department of Energy Office of Legacy Management personnel attended a reception at the National Building Museum in Washington, DC, to celebrate the opening of the exhibition titled Secret Cities: The Architecture and Planning of the Manhattan Project. The exhibit showcases the three “secret cities” of Oak Ridge, Tennessee; Hanford/Richland, Washington; and Los Alamos, New Mexico, which were built to accommodate the tens of thousands of people who worked on the U.S. Army Corps of Engineers Manhattan Project. The exhibit features original documents, photos, artifacts, maps, and models of the cities and examines the innovative design and construction of the cities.

The exhibit is currently open to the public and will run through March 3, 2019. For more information visit, https://www.nbm.org/exhibition/secret-cities/.
