Discover Los Alamos, a city that was once heavily guarded by the U.S. government and is now open for public tours. Learn how to join limited tours and experience the fascinating history of this unique location.
Los Alamos: A Once-Secret City
Los Alamos, New Mexico, holds a special place in history, established in 1943 and remaining under wraps until the end of World War II. During this time, over 6,000 scientists, engineers, and military personnel were brought here to participate in the Manhattan Project, the initiative that developed and tested nuclear weapons — the same weapons that were dropped on Hiroshima and Nagasaki in August 1945.
A Hidden History
In its early days, Los Alamos barely registered in population records, and all communications were sent to a remote post office. Since 1957, the city has opened its doors to the public, although areas surrounding the Los Alamos National Laboratory, a federal security center, remain highly protected.
A Remarkable Legacy
Under the leadership of Robert Oppenheimer, Los Alamos became the site for the research and development of the first atomic bomb. On July 16, 1945, the U.S. conducted its first nuclear test known as the “Trinity test.” As a result, just a month later, atomic bombs were dropped on Hiroshima and Nagasaki, leading to the deaths of approximately 130,000 to 200,000 people.
The Manhattan Project's Legacy
Not resting after World War II, Los Alamos continued its operations throughout the Cold War, developing hydrogen bombs and remains active to this day. The secrets and controversies surrounding this site have spawned numerous conspiracy theories, ranging from espionage rumors to mysterious disappearances of involved scientists.
Engaging Tour Programs
The Los Alamos National Historic Park, established in 2015, is one of three recognized sites of the Manhattan Project. What makes Los Alamos unique is that it is not just a weapons production site but also home to many historical structures. Visitors can participate in limited tours that provide deeper insights into life in a once-secret city.
