The slogan that Los Alamos uses today gives a nod to its past and present: "Los Alamos: Where Discoveries are Made." During the Manhattan Project, more than 6,000 scientists and support personnel at a secret laboratory in Los Alamos worked to design, test, and build the world’s first atomic weapons.

The secret laboratory of the Manhattan-Project era is now a well-known national laboratory in Los Alamos. It contains several historic sites from the Manhattan Project including the Slotin Building, the Battleship Bunkers, and the Pond Cabin. Visit Los Alamos Behind the Fence to learn more about public tours to these sites that are offered several times each year. There are also public sites in Los Alamos and a tour-only site in White Sands National Park that delve into the theme of "breaking scientific boundaries."
