About Manhattan Project National Historical Park
The Manhattan Project is one of the most transformative events of the 20th century. It ushered in the nuclear age with the development of the world’s first atomic bombs. Most of this development took place in three secret communities located in Hanford, WA, Los Alamos, NM and Oak Ridge, TN. Today, you can visit these three sites that make up Manhattan Project National Historical Park.
