Secret Cities: The Architecture and Planning of the Manhattan Project to open at the National Building Museum

Categories: Articles, Press

New exhibition examines the three cities built from scratch as part of the quest to develop the atomic bomb

The B Reactor at Hanford was the world’s first large-scale nuclear reactor. It produced plutonium for the device tested at the Trinity site in New Mexico on July 16, 1945, and for the bomb that was dropped on Nagasaki, Japan, on August 9, 1945. The B Reactor was permanently shut down in 1968, and is now being converted into a museum.

On May 3, the National Building Museum opens Secret Cities: The Architecture and Planning of the Manhattan Project. Through photos, artifacts, maps, and models, this new exhibition explores the vast, highly classified effort to produce the atomic bomb, with an emphasis on the three “secret cities” that were built to accommodate the many thousands of people who worked on the project. Secret Cities is open through March 3, 2019.

The Manhattan Project owed its success not only to brilliant scientific work, but also to significant achievements in architecture, engineering, planning, and construction. The effort to produce the world’s first nuclear weapon would ultimately involve hundreds of thousands of people and require large-scale, secure facilities. In order to undertake this complex enterprise, the U.S. government built three new cities from scratch: Oak Ridge, Tennessee; Hanford/Richland, Washington; and Los Alamos, New Mexico.

The speed and scale of construction of these cities were in many ways unprecedented. Influenced by the planned community movement and heavily reliant on prefabricated construction, these cities were in many ways proving grounds for emerging ideas about design and planning. Begun in late 1942, they collectively housed a total of more than 125,000 people by the end of the war in August 1945. Yet these cities appeared on no maps, and their existence was a remarkably well-maintained secret until the bombing of Hiroshima.

Secret Cities examines the cities as case studies in modern urban planning and building technology, while revealing the distinct way of life that emerged at each site. The exhibition also explores the architectural and planning legacy of the Manhattan Project, including its role in the emergence of multidisciplinary corporate architecture and engineering firms. The exhibition concludes with an overview of the postwar development of the three cities, which remain important centers of scientific research today.

This exhibition is supported in part by an award from the National Endowment for the Arts.
