The Birth of Camp Century: A Cold War Marvel
In 1959, the U.S. military constructed a hidden base beneath the Greenland Ice Sheet. Known as Camp Century, it was often called the “city under the ice.” The U.S. Army Corps of Engineers built this Cold War-era installation by carving tunnels into the ice. The underground network stretched over three kilometers, making it an engineering marvel.

Although publicly presented as a scientific research station, Camp Century had a secret mission. It served as a testing ground for Project Iceworm, a classified plan to deploy nuclear missiles under the Arctic. The goal was to create an extensive underground launch system capable of striking the Soviet Union. To sustain operations, the base relied on a portable nuclear reactor, an innovation at the time.
A Site of Mystery: CIA Operations and Hidden Activities?
While Camp Century’s official purpose was military and scientific, some researchers believe the CIA may have used it for other covert operations. There are unconfirmed reports suggesting that another classified Arctic facility, possibly linked to the CIA, was used for detaining and interrogating individuals.
Cold War intelligence activities often took place in remote locations, making it difficult to separate fact from speculation. The full extent of any secret programs at Camp Century or other Arctic sites remains unclear. Declassified records may one day reveal more about the hidden history of this icy outpost.
Challenges and Abandonment: Nature Takes Over
Greenland’s harsh environment posed severe challenges for Camp Century. The ice sheet’s constant movement made long-term stability impossible. Over time, shifting ice threatened to collapse the tunnels, forcing the U.S. military to abandon the base in 1967.
Following its closure, Camp Century disappeared beneath accumulating layers of snow and ice. Over the decades, more than 100 feet of ice buried the site. The abandoned base also left behind waste, including diesel fuel and sewage, raising environmental concerns.

NASA’s Discovery: A Frozen Time Capsule
In April 2024, NASA scientists unintentionally rediscovered Camp Century while testing advanced radar technology. Using the UAVSAR system, they aimed to map the internal layers of the Greenland Ice Sheet. The radar’s high-resolution imaging revealed detailed structures hidden beneath the ice, offering a new perspective on the long-lost base.
Previous surveys had only provided two-dimensional images, but UAVSAR’s advanced sensors painted a clearer picture. Scientists could see remnants of tunnels, living quarters, and other infrastructure. This discovery reopened discussions about the site’s historical significance and its environmental impact.
Environmental Concerns: Melting Ice and Hidden Waste
As climate change accelerates ice melt, Camp Century’s buried waste could resurface. Scientists worry about contaminants seeping into the environment, including fuel, sewage, and radioactive materials. Researchers now monitor the site closely to assess potential risks.
While the ice once served as a protective barrier, rising global temperatures could expose these hazardous remnants. Greenland’s melting ice sheet has already affected sea levels, making this issue even more pressing. Governments and environmental agencies now face decisions on whether to extract or contain the waste before it reaches surrounding ecosystems.
A Legacy of Science and Engineering
Despite its military origins, Camp Century contributed valuable scientific data. Ice cores extracted during its operation provided insight into past climate conditions. These samples remain crucial for studying long-term climate patterns and Arctic ice dynamics.
Moreover, the base demonstrated the potential of nuclear energy in extreme environments. Lessons learned from Camp Century’s construction and operation continue to inform modern engineering projects in polar regions.
A Cold War Relic with Modern Implications
Camp Century stands as a unique intersection of military ambition, scientific discovery, and environmental concern. Originally built as part of Cold War strategy, it now offers a glimpse into past climate conditions and engineering achievements.
NASA’s rediscovery in 2024 underscores its significance in both history and climate science. As Arctic ice continues to melt, the legacy of this hidden city under the ice will remain a topic of study and debate for years to come.
