Our historical museum is the oldest continually inhabited structure in town.

It is the former log and stone guest cottage for the former Los Alamos Ranch School, a prestigious and rigorous school for boys which preceded the Manhattan (atomic bomb) project lasting from 1918 to 1943.

The Ranch School was founded by Ashley Pond, a former member of Teddy Roosevelt’s Rough Riders and, thus, was based on a vigorous regime of outdoor sports and community service along with a college-prep academic curriculum.

Later the museum building served as the guest cottage during the Manhattan Project and housed many nobel-prize winning scientists.

Today the museum includes exhibits beginning with the formation of the land 1.4 million years ago, through the Ranch School, Manhattan Project and more modern Los Alamos.
