Deep beneath Greenland’s frozen surface lies the remains of a secret military base that was once part of one of the most ambitious Cold War projects ever attempted. Hidden under layers of ice and snow, this underground city was designed to bring nuclear missiles closer to the Soviet Union and give the United States a strategic advantage.Known as Camp Century, the base was created as part of Project Iceworm, a plan developed during the Cold War to build a network of missile launch sites beneath Greenland’s ice sheet.The goal was to hide hundreds of nuclear missiles under the Arctic ice, allowing them to be launched toward the Soviet Union across the North Pole.Building a military facility in one of the coldest environments on Earth was a massive challenge. Engineers carved long trenches directly into the Greenland ice, installed large arched steel structures, and then covered everything with snow and ice to hide the base from the outside world.The result was a frozen underground city made up of 21 connected tunnels stretching nearly 10,000 feet, or about 3,000 meters, through the ice. Despite its remote location, Camp Century was designed to support dozens of people living there throughout the year.Inside the icy tunnels was everything needed for daily life. The base included a chapel, hospital, movie theater, and even a hobby shop where workers could spend their free time. It was not simply a military outpost, but a fully functioning community buried beneath the Arctic landscape.One of the most impressive parts of Camp Century was its own nuclear reactor. This small reactor provided electricity for the entire facility, powering lights, heating systems, and equipment in an environment where traditional energy sources would have been extremely difficult to maintain.Although the base was created for military purposes, it also became an important scientific research location. Scientists collected some of the first deep ice core samples there, helping researchers study Earth’s climate history and understand how the planet has changed over thousands of years.However, the dream of creating a hidden missile network beneath Greenland’s ice eventually failed. Researchers discovered that the ice sheet was constantly moving, shifting and deforming the tunnels over time.The unstable conditions made it impossible to continue expanding the facility, and Project Iceworm was abandoned.Camp Century was officially closed in 1967. The nuclear reactor was removed, but not everything was taken away. Large amounts of waste were left behind, including hundreds of thousands of liters of diesel fuel, wastewater, and other hazardous materials.Scientists believe the site may also contain dangerous substances such as PCBs and radioactive coolant from the reactor.For decades, researchers assumed the thick Greenland ice would permanently bury the remains of the base. But climate change is changing that assumption.As Greenland’s ice sheet continues to lose mass, the frozen layers covering Camp Century are slowly thinning. Scientists estimate that within the next century or two, parts of the abandoned nuclear city could become exposed again, creating a major environmental challenge.The hidden base beneath Greenland’s ice is a reminder of a forgotten chapter of the Cold War and a warning about how climate change can uncover problems that were once thought to be buried forever.
