Los Alamos History Museum
The Los Alamos Historical Society is committed to interpreting and promoting the history of the Pajarito Plateau. The Society manages the Los Alamos History Museum in the heart of downtown Los Alamos. The museum is a must-see for any visitor to Los Alamos, New Mexico who is interested in the ancient and recent history of Los Alamos.
Built as an infirmary in 1918 and later used as the guest cottage for Los Alamos Ranch School, the museum is in the oldest continually occupied structure in town. During the Manhattan Project (1943 to 1947), the cottage continued to serve as guest quarters, notably for General Leslie R. Groves, commander of the Manhattan Engineer District, whose office and residence were in Washington, D.C.
Now it serves as an award-winning, comprehensive history museum which presents our world-changing and varied history. A book and gift shop fills a former bedroom.
WHAT TO SEE
The Museum tells the stories of those who were to arrive on the Plateau. Visitors experience where great decisions were and still are being made.
Visiting the Los Alamos History Museum can take up to 45 minutes – depending on the level of detail you are interested in. The museum has award-winning exhibits on regional geology, anthropology, the Los Alamos Ranch School founded by Ashley Pond, and the Manhattan Project.
