Camp Century, Nuclear military research base near Pituffik Space Base, Greenland.
Camp Century was an underground military facility in Greenland with 21 tunnels stretching several kilometers, housing dormitories, a kitchen, hospital, communications center, and recreation rooms. The complex used a nuclear reactor to generate power and maintain operations in temperatures dropping far below zero.
The facility was built between 1959 and 1967 as part of Project Iceworm, a classified program to create nuclear missile launch sites hidden beneath Greenland's ice sheet. The effort reflected Cold War military strategy and pushed the boundaries of engineering capability at the time.
The base served as a research facility where scientists extracted ice core samples from deep within the ice sheet to understand past climate shifts. This work allowed researchers to read Earth's climate story stretching back many thousands of years.
Access is challenging because the facility lies in an extremely remote location deep within the ice sheet, requiring extreme caution for any visit. Information about tours is limited because the site still carries restricted status and special safety requirements.
Engineers built the facility using cut-and-cover trenching techniques, creating parallel underground passages protected by layers of snow and ice. This innovative approach made it possible to operate a functioning base in one of Earth's harshest environments.
