  • In 1943, hundreds of people converged on a desert in New Mexico to work on the Manhattan Project. 
  • Building the atomic bomb required a furious working pace and the utmost secrecy. 
  • It also forever changed the landscape of Los Alamos and the lives of its residents. 

Though Los Alamos was just one of many sites dedicated to the Manhattan Project, it was the most remote, and the most secret.

Located in the desert, it has mountain views and vivid sunsets. It's where scientists prepared the bomb for the Trinity Test.
